Nonlinear magnetostatic waves (MSWs) have recently received considerable attention for their potentialities in microwave signal processing through the generation of phenomena like modulation instability and solitons, typical of optical devices too. In this paper, the generation of MSW solitons is analyzed from a theoretical and experimental point of view, giving an engineering approach of the problem. The nonlinear Schrödinger equation (NLSE) used for describing the physical effect is here used as a basis for a circuital analysis of a MSW delay line, to model the propagation of nonlinear surface wave pulses. Experimental results are given to confirm the validity of such a model.

Abstract
Nonlinear magnetostatic waves (MSWs) have recently received considerable attention for their potentialities in microwave signal processing through the generation of phenomena like modulation instability and solitons, typical of optical devices too. In this paper, the generation of MSW solitons is analyzed from a theoretical and experimental point of view, giving an engineering approach of the problem. The nonlinear Schrödinger equation (NLSE) used for describing the physical effect is here used as a basis for a circuital analysis of a MSW delay line, to model the propagation of nonlinear surface wave pulses. Experimental results are given to confirm the validity of such a model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
