摘要:

利用互补开口环谐振器的谐振特性,设计了一种极化选择多频带人工磁导体,并采用相位对消的方法,将此新型人工磁导体和理想电导体组合,提出了一种具有极化选择特性的多频带低雷达截面积反射屏.当电磁波以水平极化和垂直极化照射该屏时,分别产生2个和3个低雷达截面积频段,具有多频段极化选择吸波特性.

关键词: 人工磁导体, 反射屏, 极化选择特性, 多频段, 雷达截面积减缩

Abstract:

A novel radar reflection screen composed of the polarization-dependent mutiband artificial magnetic conductor (PDMAMC) and perfect electric conductor cells is proposed. The PDMAMC is realized by etching a complementary split ring resonator (CSRR) on the patch of a conventional artificial magnetic conductor. Around the two/three operational frequencies of the PDMAMC-elements for different electric field polarizations, the reflection of the PDMAMC and perfect electric conductor have opposite phases, so for any normal incident plane wave the reflections cancel out. The basic principle is discussed and a sample is measured. The results show that the proposed method is feasible and effective for polarization-dependent mutiband RCS reduction.
