Abstract
The electromagnetic scattering of a normal incident monochromatic plane wave from a ''strongly'' nonlinear dielectric slab is considered. The time dynamic of the field inside the nonlinear body is studied by means of the Galerkin method. The solutions -of the Galerkin equations are calculated using the fourth-order Runge-Kutta-Nystrom method. - Their asymptotic behaviour abruptly changes its qualitative properties by continuous variation of the system parameters and a surprising wealth of different nonlinear phenomena appears. They are: bifurcation of the periodic response, subharmonic, almost-periodic solutions and chaotic dynamics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
