周期性有耗介质结构的电磁散射研究

Scattering from a Periodic Structure of Lossy Medium

本文介绍一种新的涂层隐身方法:周期涂覆方法,它与均匀涂覆方法相比,能够在不增加散射体厚度的情况下,使用现有单层有耗材料,使目标的隐身特性得以较大改善。本文运用快速傅氏变换和迭代法对一些具体例子进行了计算,并与实验结果进行了比较。

A periodic coating which is a new kind of layer stealth technology is presented in this paper. Compared with the method of one homogeneous layer, it can improve the target's stealth characteristic, by using existing one layer lossy material not adding its thickness. Some examples are computed by using a fast Fourier tranform (FFT) and inerative approach, and results compute are compared with that of examination.
