Nonlinear behavior of magnetostatic surface waves in ferrite-film multilayer structure

摘要

The nonlinear interaction of magnetostatic surface waves propagated along ferrite-film double-layer structure has been investigated theoretically. The possibility of the nonlinear directional coupler has been shown for the waveguide structure by solving numerically the coupled nonlinear Schrodinger equations. In addition, it is shown that bright soliton-like behavior can be seen in the structure.
