“…18 Boardman and Nikitov 19 pointed out that this inversion also leads to the possibility of MME solitons formed from MSSW pulses. Nikitov et al 20 reported modulational instability data which were consistent with this possibility. Uehara et al 21 modeled the MME pulse propagation in such structures based on the NLS equation.…”

“…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]).…”

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

“…Such a parametrically unstable behavior of the traveling MSW has been registered in a number of previous works. [5][6][7][8][9]11,13,24,25 The frequency and amplitude of these satellite waves depend on the wave parameters. Choosing 720 Oe as the external magnetic field, in Fig.…”

Lett. 100, 252412 (2012); 10.1063/1.4730374Mode-conversion enhancement of guided optical waves by magnetostatic surface waves propagating collinearly in obliquely magnetized bismuth-doped yttrium-iron-garnet film waveguide First-order parametric instability, modulation instability and second-order instability processes for magnetostatic surface waves propagating in a pure yttrium iron garnet film are investigated in accordance with the relationship between the magnetostatic wave frequency and the internal magnetic field. The transitions from the second-order parametric instability, via the modulation instability, to the first-order parametric instability ͑when the magnetic field is 720 Oe and the carrier frequency varies from 3.87 to 4.39 GHz͒, and the transitions from the first-order parametric instability to the second-order parametric instability via the modulation instability ͑when the carrier frequency is 3.5 GHz and the magnetic field varies from 427 to 647 Oe͒ are experimentally observed and explained. Dispersion characteristics of the magnetostatic surface waves are modified by introduction of a metallic ground plane in order that the Lighthill criterion, as one of the prerequisites for onset of the modulation instability, is fulfilled in a limited frequency range. Characteristics of magnetostatic surface wave modulation instability are studied by solving the nonlinear Schrödinger equation. Dependencies of the modulation frequency induced by the modulation instability on the carrier frequency and the magnetic field are found to be consistent with experimental data.
