摘    要:随着计算机技术的发展,计算电磁学得到了极大地发展和运用。它可以通过数值计算得到描述宏观电磁场的Maxwell方程组的解,从而分析介质的电磁性能。本文介绍了空间回路网法(SNM)的基本原理和使用方法。并计算了8 GHz平面波条件下的正方形格栅结构的反射率,通过比较发现单元尺寸为半波长时,电磁波吸收性能强于1倍波长情况。

关 键 词:计算电磁学  空间回路网法  格栅结构

Abstract:Along with the development of computer technology,Computational Electromagnetics have got a great progress and use.The results of Maxwell's equation described the macroscopical EM are arrived with the numerical calculation and the study analyzes the EM field of a medium.This paper addresses the basic contents and use of the spatial network method(SNM),calculates the RCS of a square grid,and then finds that the absorbing ability of a grid structure with a half wavelength long of the cell is better than one w...
Keywords:computational electromagnetics  spatial network method (SNM)  grid structure
