Feedback stabilization of unstable propagating waves.
نویسندگان
چکیده
Propagating wave segments are stabilized to a constant size and shape by applying negative feedback from the measured wave area to the excitability of the medium. The locus of steady-state wave size as a function of excitability defines the perturbation threshold for the initiation of spiral waves. This locus also defines the excitability boundary for spiral wave behavior in active media.

An Obliquely Propagating Electromagnetic Drift Instability in the Lower Hybrid Frequency Range
By employing a local two-fluid theory, we investigate an obliquely propagating electromagnetic instability in the lower hybrid frequency range driven by cross-field current or relative drifts between electrons and ions. The theory self-consistently takes into account local cross-field current and accompanying pressure gradients. It is found that the instability is caused by reactive coupling be...
متن کاملExperimental and theoretical studies of feedback stabilization of propagating wave segments.
Experimental and theoretical studies of the excitability boundary for spiral wave behavior are presented. The boundary is defined by unstable wave segments, which are stabilized by using a negative-feedback control algorithm. A kinematic description of the constant-size, constant-shape wave segments is presented.
متن کاملUnstable Radiative - Dynamical Interactions
The interaction between trace shortwave radiative absorbers and the dynamical circulation is shown to be linearly unstable for horizontally uniform basic states with a vertical gradient in the basic state absorber mixing ratio. Two types of instability are identified, described as the advective mode and the propagating mode. The advective mode is usually unstable when the basic state absorber m...
متن کاملThe Stability of a “uniform” Amplitude Wavetrain
A narrow-banded spectrum of gravity waves propagating in one horizontal direction 4 at the surface of water with finite depth may be governed by a nonlinear Schrödinger equation 5 (NLSE). If the depth is non-uniform, the coefficients in the NLSE are variable and an additional 6 linear term due to conservation of wave action flux is present, which may act as a dissipative term 7 that causes the ...
متن کاملSeismic Behavior of 2D Semi-Sine Shaped Hills against Vertically Propagating Incident Waves
This paper presents the preliminary results of an extensive parametric study on seismic response of two-dimensional semi-sine shaped hills to vertically propagating incident P- and SV-waves. Clear perspectives of the induced diffraction and amplification patterns are given by investigation of time-domain and frequency-domain responses. It is shown that site geometry, wave characteristics , and ...
