We propose a blinking stealth method based on a phase-switched reconfigurable intelligent surface (PS-RIS), which modulates the radar echo through tailored temporal phase sequencing. By applying a tailored time-sequence modulation, the PS-RIS dynamically combines echoes from distinct phase states through weighted temporal superposition, thereby suppressing overall echo amplitude and rendering targets virtually undetectable by radar—all without the need for complex spatial encoding.

As compensation for the incompletion of the profile, a limited amount of scattering/prescribed data is provided, which, in principle, contains sufficient information associated with the missing part of the profile. The existing solvers can hardly solve this type of problem. On one hand, the well-developed forward solvers have no mechanism to accept the scattering data to recover the unknown part of the profile. On the other hand, the existing solvers for inverse problems cannot retrieve the complete profile with an acceptable accuracy from the limited amount of scattering data, even when the available part of the profile can be fed into the solvers. To overcome the difficulty, the EM forward scattering from an incompletely known dielectric scatterer is derived in this work. A deep learning scheme is then developed where the forward and inverse scattering problems can be solved simultaneously. Numerical experiments are conducted to demonstrate the performance of the proposed DL-based scheme in terms of 2-D EM scattering problems.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9125-9135"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the limitations of existing methods, including the angular spectrum projection (ASP) and least-squares method (LSM) regression, in controlling the magnitude and phase fluctuation, width, center offset, and outside field level of the UMF, this article proposes a spatial-convolution-based manipulation technique with natural zero-phase constraint. The windowed Fourier theory is introduced to establish the explicit relationship between the spatial spectrum truncation window function (SSTWF) and the UMF, achieving manipulation over these metrics. Furthermore, a spherical-shell antenna array configuration is designed to generate quasi-plane waves (QPWs) for UMF synthesis, which overcomes the shortcomings of the conventional method in the synthesis region width and the spatial spectrum coverage. Finally, the array excitation was derived via the transmission matrix model, forming a complete process from the generation of plane waves to the synthesis of UMF. The effectiveness and robustness of the proposed method are validated by a 1-D prototype and supported by 2-D full-wave simulations.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9910-9922"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying a mode-matching approach at the junction between two uniform waveguides, we derive a system of linear equations for the mode conversion coefficients. The closed-form expressions for the mode conversion coefficients and phase deviations are obtained for both transverse magnetic (TM) and transverse electric (TE) polarized modes by solving these equations. Numerical results for the mode conversion coefficients and phase deviation are given. Computations show that as the frequency and waveguide thickness difference increase, the mode conversion coefficient and phase deviation increase. Under the same conditions, the conversion of the incident fundamental mode to the higher order modes remains relatively low, with the higher the order, the lower the conversion. Besides, an increase in the conductivity of the medium at the lower boundary of the waveguide will result in a decrease in the mode conversion coefficient.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9236-9246"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All cylinders are infinitely long and share a common z-axis. However, each cylinder can have a different cross section with an arbitrary shape and different gyrotropic material properties, i.e., both gyroelectric and gyromagnetic anisotropies are considered. The solution to the problem combines the following three elements: 1) development of a superpotentials-based cylindrical vector wave function (CVWF) expansion to express the EM field in the gyrotropic region; 2) utilization of the extended boundary condition method (EBCM) to account for noncircular cylinders; and 3) use of Graf’s formulas, specifically adapted for the CVWFs, to apply the EBCM at each cylinder. The developed theory allows us to calculate various scattering characteristics, including the scattering and extinction cross sections and the multipole decomposition, enabling the design and in-depth investigation of various contemporary engineering and physics applications. The method is exhaustively validated with analytical techniques and COMSOL Multiphysics. The computational performance is also discussed. Finally, we study a potential microwave application of the MS by ferrite configurations, and demonstrate broadband forward scattering by introducing oblique incidence and anisotropy. Our method may be used to analyze, design, and optimize contemporary microwave, optical, and photonic applications by beneficially tailoring the scattering properties via oblique incidence and anisotropy.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9247-9257"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although reflection amplifiers mitigate power consumption, their integration presents significant challenges. To address these limitations, this work leverages the low-power advantage of reflection amplifiers to propose a highly integrated gain metasurface design method. By integrating the reflection amplifier with the metasurface into a unified design, independent control of amplitude gain is achieved. The efficacy of this method is rigorously validated via simulations and experimental measurements. Experimental validation through wireless data transmission tests demonstrates that gain metasurfaces with partial gain elements keep superior performance compared to conventional metasurfaces, even when contrasted between passive and sparse-activation configurations. Through the incorporation of coupling considerations, the proposed sparse-gain metasurface design significantly enhances the degrees of freedom for manipulating electromagnetic (EM) waves and provides a new solution paradigm for addressing the limitations imposed by nonoperational elements in EM metasurfaces.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9146-9158"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the structure generation stage, the basic EM principles of antennas, such as wavelength constraints and impedance matching requirements, are transformed into dozens of topology-guided patterns. These patterns are then fed into a generative adversarial network (GAN) for pre-learning, thus effectively suppressing invalid structures and enhancing design efficiency. The EM-IMNN significantly alleviates overfitting and reduces the regression error by 90%. The GAN-based generator achieves a structure validity rate of nearly 100%.

In the first operating mode, the FSS functions as a time-modulated surface by applying a square-wave bias to integrated p-i-n diodes, generating stronger first-order sidebands while suppressing the reflected fundamental frequency component. This behavior enables effective Doppler spoofing over the frequency range of 1.7–3.4 GHz. In the second operating mode, the FSS operates as a checkerboard surface for radar cross section (RCS) reduction through scattering cancellation. This mode is realized by applying a continuous DC bias to the p-i-n diodes, producing alternating <sc>on</small> and <sc>off</small> states across four diagonally arranged sections of the surface. The resulting checkerboard configuration achieves significant RCS reduction within the 1.8–3.3-GHz band. The multifunctionality is enabled by a carefully designed biasing network that allows seamless switching between the two modes without structural modification. The proposed FSS is fabricated and experimentally validated, and the measured results show good agreement with simulations. Overall, the presented multifunctional FSS offers a versatile and practical solution for combined Doppler spoofing and RCS reduction in advanced radar countermeasure systems.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"10097-10102"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
