We propose an approach for the design of resonant cavities employed in magnetophotonic crystal (MPC) circulators and isolators. Starting from the analysis of a model circularly symmetric cavity, we show how to obtain a significant splitting of the eigenfrequencies of the two counterrotating cavity modes without introducing subdomains magnetized in opposite directions. Using the multiple-scattering method extended to handle uniaxial gyrotropic materials, we demonstrate numerically an MPC circulator working in a uniform external magnetic field.
我们提出了一种用于设计在磁光光子晶体（MPC）环行器和隔离器中使用的共振腔的方法。从对模型的圆形对称腔的分析出发，我们展示了如何在不引入沿相反方向磁化的子域的情况下，显著地分裂两个反向旋转腔模式的本征频率。我们使用扩展到处理单轴各向异性旋磁材料的多次散射方法，数值证明了在均匀外磁场中工作的 MPC 环行器。
