Abstract
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.
