The magneto-optical photonic crystal composed of the periodic arrangement of the magneto-optical medium (M) and the dielectric (G) shows a strong optical localization, and recently it has been widely used to realize the magneto-optical isolator. This method can be used to calculate the transmission matrix of polarized light in anisotropic media. The optical properties of the symmetric multi-defect magneto-optical multilayer isolator are calculated by this method. It is found that as the number of defects increases, The spectral response of the crossover rate is improved.When the defect is increased to a certain number, the requirement of the reflective magneto-optical isolator can be achieved without the need of an additional reflective layer
