摘要: 对于电小厚度的平面分层介质,在电磁波垂直入射情况下,根据边界条件把中间层介质等效为一层得到了有效介电常量和有效磁导率的表达式,为分析电磁波在多层介质中的传播问题提供了一种有效方法.

关键词: 有效介电常量, 有效磁导率, 反射系数, 透射系数

Abstract: For small electric thickness planar layered medium and electromagnetic waves in normal incidence,the effective permittivity and effective permeability of the middle layers media equivalent to one are obtained based on the boundary conditions.This is an effective approach to analysis problem of electromagnetic waves propagation in multilayer media.

Key words: effective permittivity, effective permeability, reflection coefficient, transmission coefficient
