摘要

本文提出了一种用于c波段应用的超薄双带极化不敏感超材料吸收体。所提出的结构包括在金属接地介质衬底的顶表面上的方形环路和改进的分环谐振器。设计的吸波器在5.4 GHz和6.1 GHz频段的厚度分别为λ0/56和λ0/49，其中λ0为自由空间波长。由于对称的几何结构，所提出的结构对偏振角的变化不敏感。它还提供了稳定的响应斜入射下的TE和TM极化高达60°。最后对所提出的结构进行了制作，在正入射和斜入射下的实验结果与模拟结果吻合较好。

Ultra-thin dual-band polarization-insensitive metamaterial absorber for C-band applications

This paper presents an ultra-thin dual-band polarization-insensitive metamaterial absorber for C-band applications. The proposed structure comprises of a square loop and a modified split ring resonator on the top surface of a metal grounded dielectric substrate. The designed absorber offers low profile with a thickness of λ0/56 and λ0/49at 5.4 GHz and 6.1 GHz, respectively, where λ0 is free space wavelength. The proposed structure is insensitive towards variations in angle of polarization due to symmetrical geometry. It also offers stable response under oblique incidence for both TE and TM polarization up to 60°. Finally, the proposed structure has been fabricated and experimental results are in good agreement with simulation results under normal as well as oblique incidence.
