MICROWAVE REFLECTION FROM SHOCK-PRODUCED PLASMAS,
Abstract
Reflection measurements have been made of very low-power, X-band microwaves axially incident on shock-produced xenon and krypton plasmas. The electron density profile at the advancing shock front was measured with a special high resolu tion transverse 60 kmc interferometric probe. On comparison with free space exponential plasma microwave interaction theory, the measured re flection coefficients were always found to be very significantly lower than the theoretical values, the greatest disagreement being at the lowest plasma densities. It is concluded that the theoretical development of non-uniform plasma-microwave interactions within a conduct ing wall non-resonant container, would permit a better comparison of theory with experiment. It also appears that more may have to be known about shock front (electron ramp) electron temperatures and electron collision frequencies before exact comparisons between theory and experiment are possible.
