“…Most soliton experiments to date, however, have involved the application of input pulse signals and the observation of the soliton pulses which evolve as a result of these inputs. Many such experiments have been done for microwave magnetic envelope (MME) solitons in magnetic films of yttrium iron garnet (YIG) (see, e.g., [4][5][6][7][8][9][10][11] and literature therein). In all of these experiments, externally applied microwave pulses were used to produce the solitons.…”

The self-generation of microwave magnetic envelope solitons in magnetic films has been realized for the first time. Solitons with a width of 20 ns and a carrier frequency of 5.1555 GHz were generated for the magnetostatic backward volume wave (MSBVW) configuration in a 5.2 mm thick yttrium iron garnet film. The film and MSBVW propagation structure were part of a ring with an overall gain of 14 dB. Pulse modulation at 10 MHz provided the interrupted feedback and the active mode locking which was needed to produce a stable and continuous stream of self-generated soliton pulses. Pulse width and phase measurements confirmed the soliton nature of the self-generated pulses.[S0031-9007(98)

Self-Generation of Fundamental Dark Solitons in Magnetic Films

The self-generation of single, fundamental, stable, spin-wave-envelope black and gray dark solitons has been realized for the first time. These solitons were generated from microwave magnetostatic surface waves (MSSWs) propagated in an in-plane magnetized yttrium iron garnet film MSSW delay line in a resonant ring. These fundamental dark solitons were made possible by a new and general filtering technique for a high gain nonlinear resonant ring. The amplitude and phase profiles together with the power spectra of the self-generated microwave pulses confirm their fundamental dark soliton nature.

“…Modulation instability has been observed in many physical systems, encompassing optical fibers [18], non-linear magneto-static waves [19,20], etc., and it is originated by small second order terms in the high frequency signal propagating in a dispersive medium. The analytical frame for the above mentioned effects is the nonlinear Schrodinger equation, where non-linearity and dispersion play a key role in the kind of effects which can be detected, and both instabilities and solitons could be obtained (see, for instance, [21]). Following this approach, the propagation of the signal through the RF transmission line could be described by a plane wave equation, including non-linear corrections due to the mechanical coupling between the RF propagating signal and the suspended beam.…”

Modulation instability generated by mechanical frequencies in RF MEMS switches is predicted and its potential contribution to the RF signal degradation is discussed. In particular, evaluations have been performed for double clamped configurations in shunt capacitive devices. As a conclusion, it is evidenced the possibility for the excitation of satellites affecting as noise sources higher than −40 dB the spectral purity of microwave sources
