频域分波法研究涂覆于金属表面的手征介质层的电磁反射特性

Investigation on the Electromagnetic Reflecting Characteristics of Stratified Chiral Media Coated on Metal by Using Wave-Splitting Method in Frequency Domain

本文利用频域分波法研究了平面电磁波入射时涂覆于金属表面的无限大层状手征介质的反射特性．频域分波法是电磁场领域新近发展起来的一种计算方法，其特点是在频域内通过数学物理变换把平面电磁波分为前行波和后行波，从而清晰地了解介质中电磁波的传输特性．本文通过理论推导和数值计算，得出了一些有用的结论，为设计防电磁波反射涂层提供了理论指导．

The electromagnetic reflecting characteristics of a plane wave incident on an infinite stratifiedchiral medium coated on metal are investigated by using Wave-Splitting Method in freqUency domain, a newlydeveloped method for computation of electromagnetic fields. Forward-and backward-going modes are identified byapplying physical and mathematical transformation on Plane wave so that the propagating characteristics of electromagnetic wave in chiral media are shown clearly. Some useful conclusions are obtained through deduction andcomputation, which provide theoretical guidance for designing anti-scattering coating.
