Linear and Nonlinear Theory of Grid Excitation of Low-Frequency Waves in a Plasma
The steady-state excitation of longitudinal waves by a pair of idealized grids immersed in a collisionlcss plasma and driven at a frequency small compared with the ion plasma frequency is investigated theoretically. In linear theory the Fourier-inversion integral which determine the spatial behavior of the potential in the plasma is expressed as a sum of two integrals which embody the interacti...
متن کاملParametric Excitation of Low Frequency Waves in ICRF-Produced Plasmas on GAMMA 10
In high power ICRF experiments on the GAMMA 10 tandem mirror, plasmas with a strong temperature anisotropy are produced when the cyclotron resonance layer exists near the midplane of the central cell. Saturation of the diamagnetism is sometimes observed when the heating ICRF power is increased. In the plasmas with the strong temperature anisotropy, Alfvén-ion-cyclotron (AIC) modes are spontaneo...
متن کاملLow-frequency excitation of double quantum dots
We address theoretically adiabatic regime of charge transport for a model of two tunnel-coupled quantum dots connected in series. The energy levels of the two dots are harmonically modulated by an external potential with a constant phase shift between the two. Motivated by recent experiments with surface-acoustic-wave excitation, we consider two situations: (a) pure pumping in the absence of ex...
متن کاملInitiation Of Excitation Waves
The thesis considers analytical approaches to the problem of initiation of excitation waves. An excitation wave is a threshold phenomenon. If the initial perturbation is below the threshold, it decays; if it is large enough, it triggers propagation of a wave, and then the parameters of the generated wave do not depend on the details of the initial conditions. The problem of initiation of excita...
متن کاملV-waves of excitation
In this paper we communicate recent developments in theory, experiment, and computer simulations of V-shaped waves in excitable media. The waves appear as the result of oblique collisions of two plane waves, and constitute a one-parametric family of V-like patterns distinguishable by the angle of collision. The shape and position of V-patterns are stable with respect to localized perturbations ...
