Bistable Microwave Oscillator Based on Nonlinear Magnetostatic Wave Transmission Line

Nonlinear Fano resonance and bistable wave transmission.

We consider a discrete model that describes a linear chain of particles coupled to a single-site defect with instantaneous Kerr nonlinearity. We show that this model can be regarded as a nonlinear generalization of the familiar Fano-Anderson model and it can generate amplitude-dependent bistable resonant transmission or reflection. We identify these effects as the nonlinear Fano resonance and s...

Propagation of Compound Signals via a Nonlinear Magnetostatic Wave Transmission Line

Pulse Wave Propagation in Bistable Oscillator Array

A study of propagating wave phenomenon in coupled systems is one of the familiar topics of research. There exist propagating wave phenomena in various systems such as reactiondiffusion systems (Nishiura et al.; 2005; Comte et al.; 2001), coupled map lattice (Kaneko; 1993) and coupled oscillator systems (Hikihara et al.; 2001; Yamauchi et al.; 1999), etc.. They are important not only in a pure n...

Overmoded GW-Class Surface-Wave Microwave Oscillator

Results of theoretical and experimental studies of a GW-class, large diameter microwave oscillator are presented. The device consists of a large cross-section (overmoded), slow-wave structure with a unique profile of wall radius specifically designed to support surface waves and to provide a strong beam-wave coupling at moderate voltage (500 kV), an internal adjustable microwave reflector, a co...

Noise effects on gap wave propagation in a nonlinear discrete LC transmission line.

We report here the results of numerical investigation of noise effects on the propagation in a nonlinear waveguide modeled by a discrete electrical line. Considering a periodic signal of frequency exceeding the natural cutoff frequency of this system, we show that noise can be used to trigger soliton generation in the medium. Besides the classical stochastic resonance signature exhibited by eac...
