Abstract:

The measurement of free electron densities and collision frequencies in ionized gas flows by a probing transverse microwave beam is described. Interpretation of the observed reflection and transmission coefficients and their phases is developed on the basis of an idealized plane wave-plane slab model, for which typical results are displayed. Application of the device and technique to the build-up of ionization behindA STRONG SHOCK IN ARGON IS OUTLINED. Effects of various departures of the microwave radiation patterns and flow configurations from the slab assumptions are discussed and examples evaluated. Author
