The unit cell can realize 1-bit reconfiguration within the frequency range of 6.15 GHz to 23 GHz, achieving polarization rotation while maintaining cross-polarized coefficients above −1 dB. The electromagnetic waves can be rotated by 90° and reflected with a 180° relative phase difference by the active PRRS in both states. The active polarization rotation performance is initially realized through the use of metal strips integrated with p-i-n diodes. The vertical interconnect access is reused to realize dc bias and enhance the unit's RF performance, introducing an additional resonance. The active PRRS is applied to radar cross section (RCS) reduction to validate its performance. Simulation results demonstrate that the directions of the RCS peaks can be dynamically controlled. A monostatic RCS reduction exceeding 10 dB is achieved across the frequency range of 6.1 GHz to 23 GHz, compared to an equal-sized metal plate.

However, strong scattering can also occur due to diffraction peaks generated by periodic structures under grazing incidence. In this letter, we present a hyperuniform radiation-scattering meta-device (HRSMD) that effectively maintains in-band radiation while reducing out-of-band scattering at grazing incidence. The proposed unit consists of a U-shaped antenna and a 5 × 5 meta-atom array loaded with 100 Ω resistors. A hyperuniform distribution is introduced to arrange all units, effectively suppressing diffraction peaks caused by a periodic array under grazing incidence. The proposed HRSMD behaves like a periodic array while resembling a random array with a disordered spatial configuration. The fabricated sample shows a maximum measured gain of 16 dBi at 3 GHz, maintaining comparable radiation performance to a periodic array with the same aperture size. Additionally, we have fabricated a low-scattering carrier to investigate the scattering performance of the HRSMD at grazing incidence. Compared to the periodic array, the HRSMD effectively reduces the radar cross section (RCS) by an average of 6 dB (horizontal polarization) and 8 dB (vertical polarization) under grazing incidence from 8 GHz to 12 GHz. At specific frequencies, the maximum RCS reduction reaches 26 dB and 31 dB for horizontal and vertical polarizations, respectively. The proposed HRSMD has significant potential for stealth applications involving periodic/nonperiodic arrays at grazing incidence.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 7","pages":"2094-2098"},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technique entails the attachment of just two thin, high-permittivity dielectric slabs to the sides of the truncated LL, maintaining the original permittivity distribution of the lens, which ranges from 1 to 2. These high-permittivity dielectric slabs cause an upward shift of the focal points, leading to a focal plane near the truncated surface, with an increased curvature radius. As a result, the phase centers of the feed elements remain closely aligned with the lens's focal points, which is crucial for sustaining high gain and minimizing gain variation. To validate the concept, a nine-element patch antenna array was integrated with the lens to enable beam scanning, and the entire assembly was processed using low-loss printed circuit board technology. Measurement results demonstrated a peak realized gain of 14.09 dBi, with a gain fluctuation of only 0.6 dB across a broad beam-scanning range of ±67° at 30 GHz.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 7","pages":"2119-2123"},"PeriodicalIF":3.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 this work, we built a nonlinear magneto-thermal coupling model for the near-field radiation of the ME antenna. The model relates temperature to the magnetization, strain, stress, as well as the electric and magnetic fields in space. The radiation performance under different temperatures was discussed. The result shows that by setting an appropriate temperature, the radiation ability can be significantly improved.
