Simulation of Ionospheric EM-Plasma Interaction in a Large Laboratory Device

Abstract

The evolution of cavitons in two-dimensions is studied by measuring the space and time development of the caviton electric field. For low power drivers the caviton is found to have an Airy function type shape which is stable in time. When a high power driving electric field is used, however, the caviton shape becomes chaotic due to nonlinear modification of the density profile. In two-dimensions, the caviton electric field is seen to develop a component in the direction perpendicular to the driving field; the initial azimuthal symmetry of the caviton is also destroyed.
