摘要： 铁磁薄膜波导中的静磁表面波和体波是色散的,波矢显示各向异性.一般,静磁波的能流方向与传播波矢非共线.文中研究分析了静磁表面波和体波的能流方向随频率和外偏置磁场方向的变化规律.

Abstract: The magnetostatio surface and volume waves are dispersive in ferrimagnetio film wave guide and exhibit wave vector anisotropy go that, in general,the energy flow and wave veotor are noncollinear. Theoretical investigation is made in this paper of variations of the direction of energy flow of magnetostatio surface and volume waves with the changes of the direction of the biasing magnetic field.

Key words: magnetostatic surface wave, magnetostatic volume wave, ferrimagnetic film
