Abstract

In this paper, we present a basic model of robust one-way electromagnetic modes at microwave frequencies, which is formed by a semi-infinite gyromagnetic yttrium-iron-garnet with dielectric cladding terminated by a metal plate. It is shown that this system supports not only one-way surface magnetoplasmons (SMPs) but also a one-way regular mode, which is guided by the mechanism of total internal reflection. Like one-way SMPs, the one-way regular mode can be immune to backscattering, and two types of one-way modes together make up a complete dispersion band for the system.

摘要

在本文中，我们提出了一种微波频率下稳健单向电磁模式的基本模型，它由一个半无限大的具有介质包层且由金属板终止的旋磁钇铁石榴石构成。结果表明，该系统不仅支持单向表面磁等离子体激元（SMPs），还支持一种由全内反射机制引导的单向正则模式。与单向SMPs一样，单向正则模式也能免受背向散射的影响，并且这两种单向模式共同构成了该系统的一个完整色散带。
