摘要

当人工磁导体和完美电导体周期性地排列在棋盘上时。人工磁导体(AMC)反射波与完美电导体(PEC)反射波的相位差为180°。所以它的雷达横截面很低。如果被这种类型的AMC覆盖，其RCS会明显降低，给检测带来困难。为了检测低RCS目标，研究了AMC表面的时域散射。研究发现，在初始阶段散射的振幅很大。过了一段时间它就变低了。我们称这种现象为时域电磁溅射效应。本文采用等效电路的方法对时域后向散射进行了分析。设计了一套测量时域溅射效应的实验系统。

Study on time domain electromagnetic sputtering effect from low RCS chessboard surface with EBG structure

When the artificial magnetic conductor and perfect electric conductor are periodically arranged in checkboard. The phase difference between the reflected wave from artificial magnetic conductor (AMC) and perfect electric conductor (PEC) is 180°. So its radar cross section is very low. If the target covered by this type of AMC, its RCS can be reduced significantly, which brings difficulty for detection. To detect low RCS target, the time domain scattering from AMC surface is studied. It is found that the amplitude of the scattering is very large in the beginning. And it becomes low after a while. We call this phenomenon the time domain electromagnetic sputtering effect. In this paper, the time domain backward scattering is analyzed by the equivalent circuit method. The experimental system is designed to measure the time domain sputtering effect.
