In this article, the magnetized plasma in 1-D ternary periodic photonic crystals is utilized as a kind of single negative material whose real part of permittivity is negative. Some discrete resonant peaks with high transmittance can be observed in the transmission band due to the evanescent wave coupling between plasma layers and dielectric layers. The nonreciprocal effect can be achieved by injecting counter-propagating TM waves into the proposed structure whose time-reversal symmetry and space-reversal symmetry are broken. The transmission band of nonreciprocal evanescent waves can be modulated dynamically due to the tuning of the period number, the plasma frequency, the plasma cyclotron frequency, the filling factor of plasma, and the incident angle. The simulation results indicate that the proposed structure can achieve 100% transmission and strong nonreciprocity, which can supply multichannel unidirectional filters with theoretical references.

基于一维三元磁化等离子体光子晶体的新型梳状非互易消逝波滤波器

本文将一维三元周期光子晶体中的磁化等离子体作为一种介电常数实部为负的单一负极材料。由于等离子体层和介电层之间的倏逝波耦合，在传输带中可以观察到一些具有高透射率的离散共振峰。通过将反向传播的 TM 波注入到时间反转对称性和空间反转对称性被破坏的拟议结构中，可以实现非互易效应。由于周期数、等离子体频率、等离子体回旋频率、等离子体填充因子和入射角的调谐，非互易渐逝波的传输带可以动态调制。
