极化相关透光吸波超构表面设计与隐身研究
Design of a polarization-sensitively and optically transparent absorbing metasurface and its stealth performance
摘要
Abstract
To fulfill the equipment of electromagnetic stealth and achieve broadband absorption,a polarization-sensitively and optically transparent absorbing metasurface is proposed in this paper.The metasurface features a sandwich structure comprising two polyethylene terephthalate(PET)layers patterned with distinct indium tin oxide(ITO)geometries,which encapsulates a polyvinyl chloride(PVC)interlayer.The metasurface exhibits polarization-sensitive absorption and excellent optical transparency due to the asymmetric rectangular ITO patterns combined with transparent materials.Simulated results demonstrate that the metasurface achieves an absorption rate exceeding 90％for x-polarized waves within 24.5-30.5 GHz,while maintaining absorption below 0.5 for y-polarized waves in the same band.A 6×6 planar array is subsequently constructed.Monostatic radar cross-section(RCS)of the metasurface and a metal plate with same size is simulated under normal and oblique incidences.The results reveal significant RCS reduction for x-polarized waves in 24.5-30.5 GHz,with peak reductions of 30 dB(normal and oblique angle of 30°).For y-polarized incidences,the pronounced RCS reduction occurred in 35-40 GHz,reaching maximum reductions of 20 dB(normal and oblique angle of 30°).This metasurface exhibits broadband and polarization-sensitive absorption with optical transparency.It thereby offers a novel material for advanced camouflage applications.关键词
