By implementing suitable periodic modulation, some specific slow wave structures can transmit slow waves at lower frequencies and radiate fast waves at higher frequencies. The technique of effective control over the slow and fast wave regions is developed, enabling the design of periodic LWAs that can excite fast waves in distinct frequency bands. By integrating these LWAs, a novel antenna design with multiple frequency-scanning bands is achieved. To validate the proposed approach, a dual-band periodic LWA based on a glide-symmetric double-layer Z-shaped spoof surface plasmon polaritons (SSPPs) structure is designed, fabricated, and measured. The measured results show good agreement with the simulated ones, demonstrating large frequency-scanning ranges, good impedance matching, and stable gain performance across both bands. Building on the dual-band design, a tri-band antenna (TBA) is further developed and simulated using the same methodology, and it has the potential to be extended to an arbitrary multiband periodic LWA. Besides, another design example, based on a different slow wave structure, is also provided to demonstrate the general applicability of this approach.

However, MTS reflectors typically suffer from chromatic aberrations with the reflected angle shifting as the frequency varies. Herein, we design achromatic MTSs for anomalous reflection by using an integral-equation framework that fully accounts for the frequency dispersion of the individual scatterers (unit cells). Rather than engineering the dispersion of each MTS cell locally, we harness the emerging near-field interactions (evanescent waves) between the scatterers to realize anomalous reflection at a fixed angle over a wide frequency range. Three anomalous reflectors are designed and experimentally verified at 10 GHz, demonstrating high-performance metrics compared to traditional achromatic reflectors while employing simple, low-profile unit cells. The presented results pave an effective way to realize achromatic wave functionalities, such as anomalous reflection, refraction, or lensing, over a wide bandwidth with low-profile and highly efficient MTSs.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4703-4715"},"PeriodicalIF":4.6,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597962","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}

This study concluded that, when applied to overhead wire (OHW) detection in obstacle collision avoidance system (OCAS) for flying vehicles (FVs), multistatic radar cross section (RCS) from a multi-input multi-output (MIMO) radar system seems to be a way to achieve that goal. Monostatic and multistatic RCSs are derived, highlighting the advantages of multistatic RCS. A complex envelope of signals received at individual antenna active elements as a function of aspect angle is determined from a multistatic RCS scenario. The stretch processing for complex range profiles from signals received by a radar after illuminating a target is examined. The 2-D range aspect angle intensity (RAAI) maps based on stretch processing using monostatic and multistatic RCS of perfect electric conductor (PEC) OHW and circular cylinder (CC) cable obstacles are generated. Multistatic RCS improvements relative to the normal incidence are in the order of 1.5, 6, and 7 dB for the PEC CC cable physical optics (P.O.) theoretical model, the Feko PEC twisted wire, and the Feko PEC CC cable, respectively. Multistatic RCS exhibits superior signal-to-noise ratio (SNR) detection differential over all aspect angles, in the order greater than 18 dB for simulation cases, and in the order of 15 dB for experimental cases analyzed in this study; hence, the multistatic RCS is more suitable for low observable obstacles’ detection, e.g., the detection of OHW obstacles for FVs’ OCAS. Detection behavior from both our experimental measurement collections using a TIDEP-01012 radar and simulation results agree.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4716-4731"},"PeriodicalIF":4.6,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597805","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}
