This approach relies on leveraging the second-order derivatives of an objective function to achieve quadratic convergence, offering a significant improvement over gradient-based methods. Instead of computing the Hessian using a finite difference (FD) scheme, a custom-developed method of moments (MoM) solver was integrated with an automatic differentiation (AD) technique to evaluate the gradients at a much lower cost. This implementation requires minimal code modifications, rendering AD a highly attractive choice. Furthermore, when using the gradients in conjunction with the interior point method (IPM), the technique demonstrates superior convergence and requires fewer function evaluations compared to gradient descent (GD) and derivative-free optimization algorithms. This makes the approach very attractive compared to existing methods. Moreover, this method has the added advantage that it can be applied to arbitrary radiation and scattering problems and be readily paired with any optimization method. The accuracy and validity of the proposed method are verified through various application examples.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6928-6942"},"PeriodicalIF":5.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027945","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 realize electromagnetic (EM) wave manipulation, a transmit-reflect switch layer (TRSL) incorporating p-i-n diodes is introduced as the middle layer of TRSM, sandwiched by two transmission metasurfaces (TMs). By <sc>on</small>/<sc>off</small> the switches, the TRSL functions as a mesh-type ground or a polarization-filtering layer, exhibiting a reconfigurable reflective or transmissive property to the incident wave. Furthermore, the TRSM achieves 360° phase compensation and directive beam formation through combined operation of upper and lower TMs. This structure enables bidirectional radiation at a single frequency and polarization. To minimize structural complexity, an enhanced TRSM design was developed and optimized to achieve a 50% reduction in the number of p-i-n diodes. Since the independent control of bidirectional radiation by TRSL does not interfere with the phase-tuning function of two TMs, the TRSM achieves 360° phase compensation and minimizes quantization errors. Moreover, the use of p-i-n diodes, which are not directly integrated with the radiating elements, reduces insertion loss. Hence, the TRSM maintains a high aperture efficiency. A prototype was fabricated and measured to demonstrate a successful realization of the upward and downward directive beams with peak gains of 22.3 and 22.1 dBi and aperture efficiencies of 47.2% and 43.8% The proposed antenna design presents notable advantages, such as high gain, high aperture efficiency, cost-effectiveness, a simplified configuration, and electronic beam control functionality.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"7051-7056"},"PeriodicalIF":5.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036670","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}

However, slots formed by the patterned top metal layer of ceramic substrate can lead to electromagnetic radiation leakage into the substrate, thereby exciting resonance in ceramic substrate with high-permittivity. This article analyzes the electromagnetic leakage caused by slots and identifies the ceramic substrate as a coupling path for interfering electromagnetic waves. The primary resonant mode of ceramic substrate, TE<inline-formula> <tex-math>${}_{mn(p+delta)}$ </tex-math></inline-formula>, is identified as the key factor degrading the shielding effectiveness of multicavity shielding in SiP. Further analysis reveals that the quality factor (<italic>Q</i>) of the substrate can be reduced through dimensional and material optimizations, thereby mitigating coupling interference. However, it remains challenging to entirely block the coupling energy. To suppress coupling interference, a novel composite shielding structure based on substrate integrated cavity (SIC) and electromagnetic bandgap (EBG) is proposed. The EBG, constructed along the SIC walls, forms a 3-D EBG through horizontally periodic metal patches and vertically via arrays. Compared to 2-D EBG, this architecture enables multilayer resonance suppression within the substrate. Simulation results demonstrate that the proposed EBG-SIC achieves broadband suppression across 5.73–11.5 GHz within the SIC resonant cavity, and the shielding effect is verified through near-field scan experiments.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6574-6583"},"PeriodicalIF":5.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145051014","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 addition, the complying-divergence property was also extended to and successful utilized in semi-implicit FDTD methods for significantly more efficient and accurate electromagnetic (EM) computations with models containing fine structures in one or two directions. This work offers an effective implementation of the complex frequency-shifted perfectly matched layer (CFS-PML) based on a one-step leapfrog complying-divergence-hybrid implicit-explicit FDTD (CD-HIE-FDTD) method with more robust simulations to address more complicated open-domain EM challenges. The stretching factors are initially introduced into Maxwell’s equations to derive a compact 1st-order differential matrix form. Subsequently, the matrix is subjected to space-time operator splitting to establish a complying-divergence framework with a two-step iterative solution. For more numerical efficiency, we utilize the leapfrog time-stepping strategy to eliminate intermediate variables and get a one-step iterative solution. Moreover, for the aforementioned computational framework, we offer an analysis for the terms of numerical stability and complying-divergence property.

It consists of a double-layer cylindrical dielectric resonator (DR) and a symmetric reconfigurable feeding circuit. The feeding network incorporates four microstrip-coupled slots, where the microstrip lines are connected to the ground via p-i-n diodes. This innovative planar feed excites two pairs of higher order DR modes, which can be modeled as equivalent magnetic and electric dipoles (M-E dipoles). The radiation superposition from these two pairs of modes significantly enhances both the antenna gain and impedance bandwidth. Additionally, the polarization of the equivalent magnetic dipole (M-dipole) modes can be controlled by the diodes, enabling beam switching across a full 360° azimuthal plane. Consequently, this planar feeding method serves as an effective replacement for the traditional combination of a feeding probe and four slots, greatly simplifying the antenna structure to facilitate the DR fabrication. To validate the design, two prototypes of four- and eight-beam configurations were simulated, fabricated, and measured. Both prototypes demonstrate high antenna gains exceeding 10 dBi, with their impedance bandwidths greater than 14%.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6381-6390"},"PeriodicalIF":5.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061953","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}
