Magnetostatic wave soliton in the microstrip line with YIG film substrate

In this paper, the envelope soliton behavior of a magnetostatic forward volume wave propagating in a microstrip line with a YIG film substrate is discussed both experimentally and theoretically from a point of view of generation of short microwave pulse. Experiments are carried out at around a frequency of 3 GHz. It is observed that input pulse signal of 35 ns duration is compressed into 10 ns by soliton. To explain the soliton properties, simulations are carried out using the split step Fourier transform method. It is shown theoretically that observed pulse compression characteristics are caused by the nonlinear effect of the permeability in the YIG film, and that a non-uniform DC bias magnetic field is effective in reducing attenuation and to observe the compressed pulse. These results can be useful for microwave pulse compression devices or generating a microwave short pulse.
