ELECTROMAGNETIC WAVE PROPAGATION IN MAGNETIC MULTILAYERS-NON-RECIPROCAL REFLECTIONS
电磁波在磁性分层薄膜中的传播——非互易反射

A theory of EM wave propagation through magnetic multilayers and superlattices is presented based on the propagation matrix of a magnetic film. By using the P matrix, the transmission and reflection coeffcients of layered magnetic media, including: (1) semi-infinite magnetic surfaces, (2) magnetic multilayers, (3) semi-infinite magnetic superlattices, are obtained. The numerical results show that the EM modes of a magnetic layer system are excited and manifested as the sharp dips in the S-polarized reflection, and the dispersion curves of magnetic polaritons can be measured by a method similar to attenuated total reflection (ATR) technique.
