Pulse propagation in a nonlinear system on the basis of coupled magnonic crystals

Resumo

A structure on the basis of coupled magnonic crystals has been considered, for which a nonlinear model in the form of a system of nonlinear Schrödinger equations has been developed. By numerical simulation, the possibility of nonlinear branching of the signal has been shown, in which, depending on the input amplitude, pulses exit through different ports of the coupled structure. The results of this work can be used for developing magnonic crystal devices for functional processing of microwave signals.
