The resulting formulation is well-conditioned in the entire low-frequency regime, including the eddy-current one, and can be applied to arbitrarily penetrable materials, ranging from dielectric to conductive ones. In addition, by choosing the rescaling coefficients of the quasi-Helmholtz components appropriately, we prevent the typical loss of accuracy occurring at low frequency in the presence of inductive and capacitive type magnetic frill excitations, commonly used in circuit modeling to impose a potential difference. Finally, because it relies on quasi-Helmholtz projectors instead of the standard loop-star decomposition, our formulation can be used for modeling multiply connected geometries, without incurring the computational overhead caused by the search for the global loops of the structure, while also being compatible with most fast solvers. The efficacy of the proposed preconditioning scheme when applied to both simply and multiply connected geometries is corroborated by numerical examples.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"5725-5740"},"PeriodicalIF":5.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10964555","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, judicious siphoning of the microscopic nonlocality associated with such enhanced meta-atoms facilitates global control over the MS response across the entire angular range, specifically at challenging near-grazing scenarios. In this article, we introduce a rigorous closed-form methodology to realize such intricate mixtures of tangential and normal components for transverse-electric (TE) waves via a highly practical platform—printed-circuit-board (PCB) compatible cascaded admittance sheets. To this end, we derive a universal all-angular link between this MS-level composite, which leverages macroscopic nonlocality of multiple reflections, to its underlying meta-atom-level susceptibilities. We demonstrate this scheme by devising a PCB all-angle-transparent generalized Huygens’ MS radome and an all-angle perfect-magnetic-conductor (PMC) PCB MS.

Metasurfaces offer significant potential because of their strong EM wave control capabilities. This article presents a conformal array scattering theory (CAST) for precise beam manipulation on 2-D conformal coding metasurfaces (CCMs). Due to the incident wave angle and the curved surface shape, elements exist scattering shadow regions. Therefore, we investigate the spatial direction and distribution of the scattering fields from subarrays composed of 1-bit elements, while analyzing the formation mechanism of the scattering shadow regions. By incorporating wave path and reflection phase changes induced by structural bending, we establish an accurate theoretical model to compute the far-field scattering pattern of CCMs. To validate the approach, a CCM based on a graphene-assembled film (GAF) with ultrahigh conductivity and excellent mechanical properties such as flexibility and lightweight is used to fabricate the designs. The flexible GAF can provide additional spatial freedom through structural bending, enabling curvature-based scattered beam manipulation without requiring other active devices. Theoretical analysis, simulations, and measurements show good agreement, demonstrating the potential of this method for designing conformal arrays for various curved platforms.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"5481-5492"},"PeriodicalIF":5.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782116","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 metalens with single-focus phase distribution can only compensate for the first-order Taylor expansion of the outgoing beam by modulating the wavefront phase entering the lens surface, resulting in a very limited beam scanning range, and the phase error dramatically increases with the beam steering to the large angles, which suffers serious gain degradation. We, herein, proposed a novel cross-type multifocus phase compensation method to modulate the wavefront phase and increase the proportion of transmitted phase linear term to enlarge the beam steering angle. Three-focus and five-focus lenses are implemented based on the proposed phase distribution method and extend the beam scanning angle to ±48° and ±71° with a gain degradation of only 3.8 dB, respectively. A three-focus metalens is designed by employing three-bit phase-quantized metasurface units and simulated with commercial software CST Microwave Studio. The metalens operates in the frequency range of 24.25–25.8 GHz. It is capable of steering the main beam from −48° to 48° with gain degradation of 3.8 dB. The three-focus metalens is fabricated and measured, and the experimental results match well with simulated ones, which validates the efficacy of the proposed multifocusing method. Meanwhile, the influence of amplitude and phase errors of the metasurface units on the metalens performance is analyzed to fully evaluate the metalens antenna and illustrate the robustness of the proposed method.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"6062-6067"},"PeriodicalIF":5.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782023","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}

Periodic characteristic mode analysis (PCMA) is implemented to reveal the scattering mechanisms, using an X-band (8.0–12.0 GHz) antenna array as an illustration. It is found that the scattering at 8.0 GHz primarily comes from the center of the ground plane, while the scattering at 12.0 GHz is dominated by the edges of the ground plane. To reduce the scattering at 8.0 GHz, interdigital patches are integrated over the radiation aperture to create a reverse current that counteracts the scattering current on the ground plane. In addition, parasitic patches with shorting pins are introduced to convert the horizontal current into the vertical current, further suppressing the scattering at 12.0 GHz. The suppression technique is applicable for linear antenna arrays with small transverse dimensions. It does not increase the profile height and can enhance the gain of the array. The effectiveness of this technique is validated through a <inline-formula> <tex-math>$2times 8$ </tex-math></inline-formula> finite array.

However, controlling beam trajectories in the THz band has been challenging due to the complexity and high costs associated with traditional phase or amplitude modulation techniques, which often require intricate pixel-level control and result in significant losses from switching components. In this work, we introduce a novel and practical method for generating tunable Airy beams by simply proportionally adjusting the phase of a specially designed lens. This approach enables direct and precise control of the beam’s trajectory through straightforward proportional phase modulation, eliminating the need for complex modulation schemes and costly components. We fabricated three lens prototypes using high-precision 3-D printing technology to validate our method. Each lens transforms an incident plane wave into an Airy beam following a distinct parabolic trajectory determined by the proportional phase modulation. Experimental results confirm that our method can generate and control the trajectory of Airy beam. This solution may be applied to THz communication and beam manipulation, effectively addressing the challenges of trajectory control in the THz band.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"5360-5367"},"PeriodicalIF":5.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144781953","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}
