Abstract

The paper presents the results of a theoretical study of the dispersion characteristics of electromagnetic waves (EMW) existing in a transversely magnetized antiferromagnetic (AFM) semiconductor with loss. An AFM semiconductor is an infinite bi-gyrotropic medium, the effective material parameters of which are twice negative in several frequency ranges. It was found that these frequency bands are in the terahertz range, and there are four backward EMEs in them, two of which are TE waves, and the other two are TM waves.

基于反铁磁半导体的太赫兹频率范围双负介质

摘要本文介绍了对横向磁化反铁磁（AFM）半导体中存在的电磁波（EMW）的色散特性进行理论研究的结果。反铁磁半导体是一种无限双向旋转介质，其有效材料参数在几个频率范围内为两次负值。研究发现，这些频段在太赫兹范围内，其中有四个向后的 EME，其中两个是 TE 波，另外两个是 TM 波。
