摘要

解决了在外加磁场控制下铁氧体一维磁光子晶体上平面波的散射问题。基于Floquet理论，以解析形式得到了层中Hill方程的基本解。明确地求出了色散方程及其根。根据层的材料参数对结构的色散特性进行了分析。确定了太赫兹波在受周期数限制的磁光子晶体上的透射和反射系数。对得到的解进行了分析，建立了不同频率波在表面和体模下完全透射和反射的铁氧体层参数。

Ferrite Magnetophotonic Crystal for Terahertz Tunable Filter

We solved the problem of scattering of plane wave on a ferrite one-dimensional magnetophotonic crystal controlled by an external magnetic field. Fundamental solutions of the Hill equation in layers based on the Floquet theory are obtained in an analytical form. The dispersion equation and its roots are found explicitly. The analysis of the dispersion properties of the structures is carried out depending on the material parameters of the layers. The transmission and reflection coefficients are determined for the terahertz waves on a magnetic photonic crystal limited in terms of the number of periods. The analysis of the obtained solutions is carried out and the parameters of ferrite layers are established with full transmission and reflection of waves at different frequencies in surface and bulk modes.
