均匀平面电磁波的传输特性是"电磁场与电磁波"课程中教学的重点内容.特别是,均匀平面波垂直入射到平面分层媒质的讨论是平面波传输现象的核心问题之一.从经典的三层平面分层媒质的透射与散射问题出发,探究阻抗边界的透射与反射现象,并进一步扩展讨论多层阻抗边界下的透射与散射问题.通过石墨烯和频率选择表面的实例展示包含阻抗边界的平面分层媒质的反射与透射问题在吸波材料设计、天线罩设计等实际工程问题中的应用.
Discussions on Reflection and Transmission of Planarly Layered Media
Propagation of uniform plane electromagnetic wave is a key content of the course of Electromagnetic Field and Electromagnetic Wave.Especially,discussion about normal incidence of uniform plane wave on planarly layered media is one of the key problems for the plane wave propagation.Starting with a classic problem of three planarly layered media,reflection and transmission phenomena of the impedance boundary are elaborated.Furthermore,the reflection and transmission problems for multiple impedance boundaries has been discussed.The numerical examples of graphene and frequency selective surface are given to demonstrate the application of the reflection and transmission analyses of the planarly layered media with the impedance boundary into the practical engineering problems including absorbing material design and antenna radome design.
