EFFECT OF JOULE HEATING ON THE PROPAGATION OF MICROWAVES TRANSVERSE TO A FLOWING PLASMA
Abstract
An approximate analysis is made of the effect of microwave heating on the electron density dstribution and propagation characteristics of a slightly-ionized gas flowing transverse to the direction of microwave propagation. Consideration is restricted to the limiting case in which the gas is assumed to be in complete equilibrium. An analytcal solution is obtained by linearizing the equations under the assumption that the part of the Joule heating which goes into ionization is small compared to the flux of kinetic energy. Calculations are performed for typical shock tube conditions using rgon as a working fluid in order to determine what power levels would be required to observe this type of interaction. The calculations indicate that standard, off-theshelf cw X-band microwave equipment would be jut about capable of providing an interaction strong enough to be detectable. (Author)
