Abstract
Transmitted power dependence of magnetostatic surface-wave propagation has been numerically investigated with the help of the finite-element method. The solutions in the weakly-nonlinear regime are compared and shown to be in good agreement with the results from the quasi-linear approximation in conventional perturbation methods. In addition, the power dependence of the propagation constants is also shown in the strongly nonlinear regime.
