英文摘要：
The polarization properties of a magnetophotonic crystal at the frequencies located in the vicinity of ferromagnetic resonance are studied. The investigations are curried out taking into consideration the fact that the magnitude of material losses in ferrite layers at this frequency band is significant. The method is based on obtaining a system of ordinary differential equations and further analyzing the stability of solutions of this system. The electromagnetic properties of the structure under study are found out via the analysis of the eigenvalues of the transfer matrix of the structure period. On this basis the boundaries of the stopbands and passbands of the eigenwaves are determined. The frequency and angular dependences of the reflection and transmission coefficients are given. The angle of the rotation of the polarization plane and the ellipticity of the reflected and transmitted fields are obtained.
