We investigated the magnetic polaritons in a semi-infinite ferrite-semiconductor binary structure at the microwave region of the spectrum. The permittivity and permeability tensors of the structure depend on the various factors including the characteristic frequencies of the semiconductor and ferrite material, the thickness ratio of two layers, the external magnetic flux density and its frequency. By changing these factors, we can control the optical properties to achieve some extraordinary behaviors. By controlling and adjusting some accessible factors, the longitudinal components of both permittivity and permeability tensors simultaneously acquire zero. This region is identified as the gyrotropic nihility region. At this region, the waves can easily pass through this structure as its resistance to the passage of the electromagnetic waves is negligible. In this paper, we have studied the circumstances under which this extraordinary phenomenon may occur.

BaM/6H-SiC多层结构中回旋虚无的有效质量依赖性
我们在光谱的微波区域研究了半无限铁氧体-半导体二元结构中的磁极化子。该结构的介电常数和磁导率张量取决于多种因素,包括半导体和铁氧体材料的特征频率、两层的厚度比、外部磁通密度及其频率。通过改变这些因素,我们可以控制光学特性以实现一些非凡的行为。通过控制和调整一些可接近的因素,介电常数和磁导率张量的纵向分量同时为零。该区域被确定为回旋虚无区。在这个地区,波可以很容易地通过这个结构,因为它对电磁波通过的阻力可以忽略不计。在本文中,我们研究了可能发生这种异常现象的情况。
