英文摘要：

The dependence of propagation modes of microwave magnetostatie waves （MSWs） on the magnetization direction in magnetooptic film waveguides is analyzed comprehensively in the paper. The general expressions of frequency band and dispersion relation for any MSW mode are given. The MSW-mode figure is perfectly exhibited for the first time. The resuhs obtained can be applied to analyze how to improve the diffraction performance of the new MSW-based magnetooptic Bragg cells by inclined bias magnetic field.
