Abstract

This communication presents a design method to use low-resistive indium tin oxide (ITO) film for forming a low-profile and transparent dual-polarized frequency selective rasorber (FSR) with two ultrabroad transmission bands. The FSR designed by stacking two lossless dual-passband Frequency-selective surface (FSS) with a 2-mm air gap achieves two absorption bands by means of the interlayer coupling effect between the top and bottom FSS. The designed FSR realizes two broad transmission bands of 4.16–11.35 GHz (92.7%) and 18.89–30.06 GHz (45.6%), respectively while two broad absorption bands cover 13.54–16.58 GHz (20.2%) and 31.33–35.81 GHz (13.4%), respectively. A prototype of the proposed FSR is fabricated to verify its absorption and transmission performance, and the working principle is analyzed by combining the equivalent circuit model (ECM) with the surface current distribution. The proposed FSR exhibits the potential to reduce the out-of-band radar cross section (RCS), with its optical transparency showing promise for window applications.

采用低阻ITO薄膜的低轮廓透明超远双传输带频率选择反射器

本文提出了一种使用低电阻氧化铟锡（ITO）薄膜形成具有两个超远传输带的低轮廓透明双极化频率选择反射器（FSR）的设计方法。将两个具有2 mm气隙的无损双通带频率选择表面（FSS）叠加而成的FSR，利用顶部和底部FSS之间的层间耦合效应实现了两个吸收带。所设计的FSR分别实现了4.16 ~ 11.35 GHz（92.7%）和18.89 ~ 30.06 GHz（45.6%）两个宽带传输频段，以及13.54 ~ 16.58 GHz（20.2%）和31.33 ~ 35.81 GHz（13.4%）两个宽带吸收频段。制作了FSR样机，验证了其吸收和传输性能，并结合等效电路模型（ECM）和表面电流分布分析了FSR的工作原理。所提出的FSR显示出降低带外雷达横截面（RCS）的潜力，其光学透明度显示出窗口应用的前景。
