Abstract: 

The main nonlinear features of pulse distribution on distances a lot of smaller length of the linear energy swapping are studied in the framework of an obtained system of nonlinear Schrodinger equations what described distribution оf direct volume magnetostatic waves in two connected ferromagnetic films. The estimation оf connection between films influence оn group velocities, dispersion and nonlinearity coefficients is carry out. The problem of modulation instability in connected structure depending on distance between films is discussed. Shown, that the signal of the large amplitude is divided between connected films, the signal of small amplitude is not redistributed.
