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.
In this paper, the electromagnetic reflection characteristics of the Ω dielectric coating on the ideal conductor surface are investigated by using the frequency-domain wave-division method. The effects of the human-induced conditions and the electromagnetic parameters of the material on the electromagnetic reflection performance of the Ω medium are discussed respectively. Some useful Conclusion By numerical calculation, a double-layer dielectric coating capable of effectively preventing electromagnetic reflection in the frequency range from 9 to 11 GHz is theoretically designed.
