Abstract
Disclosure is directed to an apparatus for producing a microwave discharge n a supersonic gas flow such that the available microwave energy is deposited in the gas as completely and uniformly as possible through a substantial cross-section of the flow channel. The flow channel is provided within a waveguide and microwave energy is caused to be propagated through the waveguide substantially in the direction of the gas flow. A supersonic nozzle is provided in the channel dividing the channel into an upstream plenum and a downstream low pressure region, and the electric discharge occurs in the low pressure region just beyond the nozzle throat.
