ISED-APTF emulates the workflow of the new accurate subentire-domain (NASED) basis function method to adaptively perceive cell structures and predict current coefficients by applying the subdomain neural network (SNN) and the entire-domain neural network (ENN). SNN integrated with transfer learning can rapidly provide initial current coefficients of different subarrays for ENN to modify based on global coupling. The initial current coefficients are not only correlated with the final current coefficients but also provide prior coupling information regarding cell structure. Besides, by designing fusion schemes that integrate spatial–physics semantic information with numerical features and designing a hybrid data-physics loss function with impedance matrix equations, this work highlights an efficient application of the Transformer model for LFPSs’ problems. Numerical experiments demonstrate that the matrix equation solving process is replaced by ISED-APTF, reducing the computational time by 93.4%–99.2% in the online process while maintaining high accuracy. ENN mainly learns modification patterns for current coefficients across varying sizes and periods from PEC patch arrays, which generalize well to larger-scale arrays and LFPSs with different cell structures.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9886-9899"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131496","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}

According to a novel near-field partitioning scheme derived from the spatial distributions of active power density (APD) and reactive power density (RPD) of the antenna, the antenna’s surrounding spaces are divided into two regions, one is “strong coupling region” or radiation regulation region for loading parasitic antenna unit to enhance antenna radiation performance, another is “weak coupling region” or scattering controlling region for loading variable artificial electromagnetic structures to reduce the antenna structural radar cross section (RCS). The systematic design methodology was discussed in detail, and a typical microstrip patch antenna partition loading with parasitic patches and a polarization conversion metasurface (PCM) was designed, fabricated, and measured, validating the proposed approach. Compared to a reference patch antenna, the partition-loading antenna achieves a peak gain enhancement of 3.1 dB (reaching 9.5 dBi), an impedance bandwidth expansion from 10.76% to 23.32%, and a broadband monostatic RCS reduction of over 5 dB across the 8–16 GHz range.

Moreover, this approach is applicated to calculate the resonant characteristic of a designed basic annular all-metal CSRR structure-based FSS, which is successfully verified by experimental results. Furthermore, the basic annular-shaped CSRR is upgraded through the strategic introduction of slots, thus a heightened sensitivity to frequency changes is achieved. In addition, an example of reversable application, rooted in the skin effect modified distributed equivalent circuit approach, is delivered and further substantiated through experimental validation, which could be new avenues for designing intelligent and tunable CSRR structures.

This scheme incorporates third-degree spatial difference terms, each associated with its corresponding coefficient, into the time-stepping formulation of the M3d24 scheme. When these added terms attain second-order and fourth-order spatial accuracy, the resulting schemes are denoted as RM3d24-TD2 and RM3d24-TD4, respectively. By jointly optimizing the coefficients of the third-degree difference terms and the original coefficients of the M3d24 scheme, both RM3d24-TD2 and RM3d24-TD4 achieve low numerical dispersion errors while facilitating a further relaxation of the Courant stability constraint. However, only the RM3d24-TD4 scheme is capable of further reducing numerical dispersion error within the operating frequency band for broadband applications by selecting optimized coefficients corresponding to an appropriate grid resolution, while maintaining a fixed spatial discretization step size. Simulation results demonstrate that the proposed RM3d24 scheme maintains numerical stability and effectively suppresses dispersion errors under large Courant numbers, thereby enabling accurate and efficient modeling of long-duration and electrically large-scale problems.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9704-9717"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131741","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}

The waveguide leverages established PTD-symmetry principles while introducing a practical dual-edge realization that enables simplified excitation using standard waveguide feeders and is fully compatible with gap waveguide platforms. We provide a detailed discussion of the design, including the implementation of the required metasurfaces and the transitions necessary for efficient excitation. To validate the backscattering immunity, a bent waveguide prototype is developed, demonstrating low reflection over a relative bandwidth of 27.5%. A prototype is manufactured to experimentally confirm the robust propagation achieved in the waveguide.

An optimal flat focal plane is first determined to achieve high-performance multiple beam radiation across different elevation angles. Subsequently, a compact sublens-integrated feeding mechanism is introduced, supporting effective tilting of the feed beam in both azimuthal and elevational dimensions toward the lens center. This approach mitigates spillover losses of multiple feeds while enabling their seamless placement on the flat focal plane. A proof-of-concept prototype is fabricated and tested, incorporating 21 feed structures to achieve 21 beams distributed over a 2-D coverage. Measurement results demonstrate that all feeds can operate simultaneously with high isolations, supporting multiple independent beams with angular ranges of 360° in the azimuthal plane and about ±50° in the elevation plane. The fabricated lens antenna achieves a 3-dB gain bandwidth of 11.2% from 12.7 to 14.2 GHz, with a peak realized gain of 19.0 dBi at 13.0 GHz, corresponding to an aperture efficiency of 38%.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9636-9647"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131147","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 radiation from this region has been shown to significantly enhance antenna directivity and gain for certain lens geometries, the underlying physical mechanism has not been fully explained. To address this, a hybrid high-frequency method combining geometrical optics (GO) with stratified-media Green’s functions (SGF) is employed to analyze low-permittivity elliptical and extended hemispherical lenses. It is shown that the evanescent wave generated in the shadow region can leak energy into air tangentially to the lens surface. When this radiation aligns with the main beam and is in phase with the field from the illuminated region, constructive interference enhances both taper and reflection efficiency, leading to an overall gain increase of 2 dB for an extended hemispherical lens. The results are validated through full-wave simulations and measurements of a prototype operating at 180 GHz.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9690-9703"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131442","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}
