The slack variables are defined to limit the synthesis in a prescribed range dependent on physical and technological constraints. This aims to avoid wasting the computation resources on the synthesis solutions that cannot be implemented. To handle the singular Jacobian matrix encountered when solving the underdetermined synthesis equations, a modified two-step Levenberg-Marquardt (TSLM) algorithm is introduced to improve the synthesis robustness and efficiency significantly. Besides the classic trial step in the iterations, TSLM employs an extra approximate step in the trust region and adaptive parameters to accelerate the convergence. Compared with other algorithms, TSLM can save more than 2/3 of the computation time. Moreover, to prevent the synthesis solution vectors from clustering in a particular subspace, the least influential variables are initialized and fixed in a grid-like manner to search for multiple well-separated solutions in the global region. These well-separated multisolutions can provide distinct schemes for physical implementation. Multiple synthesis examples are presented, including cross-coupled topologies, topologies incorporating frequency-dependent couplings (FDCs), and networks with nonresonating nodes (NRNs). Finally, one fourth-order combline filter with all positive couplings is manufactured and measured to validate the proposed synthesis theories.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 1","pages":"298-308"},"PeriodicalIF":4.1,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of information encryption, electromagnetic metasurfaces are also playing an increasingly important role. This article proposes a one-time dual-authentication encryption scheme for metasurfaces based on the XOR algorithm. Compared to traditional metasurface encryption, we do not store information solely in a single degree of freedom of the electromagnetic wave, thus avoiding decryption by indiscriminate attacks from adversaries. By employing the XOR algorithm of digital systems, we divide the information to be encrypted into multiple parts, which are held by several individuals, with each part containing no useful information on its own. To decrypt the information, the collaboration of all participants is required to successfully decode the encrypted message. On this basis, we have also designed a dual-authentication decryption method that requires two layers of decryption to break the final encrypted information. The first layer of decryption not only confuses attackers but also provides a key for the second layer of decryption, achieving a dual anti-counterfeiting purpose. Moreover, due to the theoretically unbreakable nature of the one-time pad (OTP), our scheme offers extremely strong security. To validate the theoretical concept, we improved the traditional G-S algorithm, using metasurface holography as a bridge, designed theoretical simulations at the 8-GHz electromagnetic band, and conducted microwave experiments. The experimental results highly correspond with the simulation outcomes, confirming the feasibility of the concept.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 3","pages":"1741-1751"},"PeriodicalIF":4.1,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To realize the continuous wideband coverage of 2–18 GHz while avoiding the Bode-Fano limit, the proposed PA divided the full frequency band of 2–18 GHz into three continuous frequency subbands with each band covered by a sub-PA. Since each sub-PA works in a transient bandwidth that is only a fractional part of the full frequency band, it will have much higher efficiency and gain. The three sub-PAs can be merged or combined by using a reconfigurable matching network and a reconfigurable combining network so that they can be flexibly reconfigured between three frequency subbands. Based on this strategy, the proposed PA consists of a reconfigurable low-band (LB) sub-PA1 covering 2–10 GHz and a wideband high-band (HB) sub-PA2 covering 10–18 GHz. To effectively combine the two sub-PAs and eliminate the loading effect from each other, a reconfigurable output combining network and a reconfigurable input matching network were proposed. With the proposed structure, the loading effects from the inactive sub-PA to the active sub-PA can be minimized and used as a part of impedance matching to optimize the PA performance. The PA with wideband coverage and high efficiency can be simultaneously achieved using the proposed reconfigurable technique. To demonstrate the proposed techniques, a reconfigurable PA with continuous frequency coverage from 2 to 18 GHz is designed and fabricated in a 0.15-<inline-formula> <tex-math>$mu $ </tex-math></inline-formula>m gallium nitride (GaN) technology. The resulting PA has been demonstrated to have a measured average PAE of 34% across the ultrawideband range of 2–18 GHz, a peak PAE of 42.8% at 10 GHz, and the measured saturation output power Psat ranges from 31.3 to 34.9 dBm.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 4","pages":"2320-2333"},"PeriodicalIF":4.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They rely on a switched oscillator excited by a low amplitude frequency-modulated continuous-wave (FMCW) signal, which provides an approximately phase-coherent response. Due to the complexity of their operation mode, involving the start-up transient and a time-varying phase shift, their realistic modeling is demanding. Here, we present an in-depth semianalytical investigation of an SRO transponder excited by a frequency-stepped signal, which includes, for the first time to our knowledge, a thorough analysis of the noise perturbations. The SRO is analyzed with a 2-D envelope-domain formulation, derived from a current function extracted from harmonic balance. As will be shown, the SRO response to the incoming signal can be predicted with two nonlinear functions, corresponding to the amplitude and phase, obtained in a single oscillation interval. We will derive an Ornstein-Uhlenbeck system from which the variance of the SRO amplitude and phase will be determined through a detailed analytical approach. Like the SRO response, the noise behavior can be predicted with functions extracted from a single oscillation pulse, which will relate the noise effects to the unperturbed amplitude and phase at the various oscillation stages. The complete investigation provides insight into the effect of nonlinearity and noise on the detected baseband signal and the estimated distance. It will be applied to an SRO at 2.7 GHz, which has been manufactured and measured.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 1","pages":"45-58"},"PeriodicalIF":4.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10713863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the calculation process is brief and lacks verification. In addition, the radio frequency (RF)-induced current of BWs is usually approximated to that of EEDs, but the applicability still lacks validation. In this article, the input impedance of a BW EED is calculated and simulated. Using the analytical or simulated circuit model of the BW, the calculated input impedance is close to the simulated result. The measured and simulated input impedances are in good agreement. Subsequently, the Norton equivalent circuit of the connecting wires of the EED exposed to EMR is determined. After that, the induced currents of the EED and the BW are calculated using the equivalent circuit method. Then, the simulation is performed to calculate the induced current of the BW to validate the currents using the circuit model. The currents of the BW and the EED are close to the simulated result in 1–7 GHz. However, in about 7–11 GHz, there are obvious deviations between the currents, which may result from the impedance mismatch and coupling EM energy of the transmission line of the EED. The current of the BW is measured, verifying the simulated result. The influences of the aperture angle formed by the connecting wires, the polarization, and the incidence direction of EM wave on the induced current are studied using the simulation. When the aperture angle is 90°, the induced current of the BW is highest. The induced current decreases as the polarization angle increases. The influence of incidence direction on induced current depends on the antenna radiation pattern.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 4","pages":"2259-2271"},"PeriodicalIF":4.1,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the numerical method, we extract the numerical Green’s function of the multiport waveguide at one time. Different structures will be transformed into different current sources placed in the background waveguide through the least-squares method. Then, under the constraints of physical equations, we achieve the inverse solution from the design target to the metal structure. Case 1 presents an inverse-designed 1-to-3 phase-shifting power divider, proving the method’s capability for designing multifunctional electromagnetic devices. Keeping the background waveguide structure unchanged, Case 2 realizes a 1-to-3 frequency divider, illustrating the flexibility of the NGF-IDM. The experimental results show that the theoretical, simulation, and measurement results are highly consistent, proving the feasibility and effectiveness of our method.

However, their analysis is, in general, too simplified to reliably predict the behavior of transistor-based oscillators. In this work, we present a new analysis method based on numerical nonlinear models of the oscillator circuits. These models are extracted from harmonic balance (HB) with the aid of an auxiliary generator (AG). They are introduced in a formulation of the coupled system, which can rely on an analytical or numerical description of the coupling effects. The number of independent variables is reduced by expressing one of the oscillator voltages in terms of the other by means of interpolation. The complex error function is solved through contour intersections, which enables an exhaustive calculation of all the coexisting solution curves. Distinguishing between stable and unstable solutions is essential since only stable solutions will be physically observed. We present a detailed stability analysis of this coupled system based on the perturbation of this system about each periodic solution. This involves the linearization, about each solution, of the nonlinear numerical models of the oscillator circuits. Also, the phase noise is analyzed by introducing equivalent noise sources in the perturbed system and by obtaining the carrier modulation. The investigation is extended to the case in which one of the oscillators acts as a self-injection-locked tag for motion sensing. Its signal injection locks the second oscillator, acting as a receiver. The formulation addressing this case makes use of a numerical description of the coupling and reflection effects. The system has been experimentally characterized with very good results, confirming the analysis methods.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 1","pages":"130-143"},"PeriodicalIF":4.1,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10709636","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
