摘　　要：本文利用频域分波法研究了理想导体表面Ω介质涂层的电磁反射特性，并结合实例分别讨论了人射条件及材料的电磁参数对Ω介质电磁反射性能的影响，得出了一些有用的结论通过数值计算，理论上设计出了在9～11GHz的频率范围内能够有效防止电磁反射的双层Ω介质涂层.The electromagnetic reflecting characteristics of a plane wave incident on an infinite stratified Ω medium coated on metal are investigated by using Wave-Splitting Method in Frequency Domain,and some useful results are presented by examining the conditions which affect the reflecting characteristics.Finaly,we have designed theoretically anti-EM Ω reflection coating which can elfciently absord EM energy in a broad frequency range.
