Abstract:

The Plasma Research Group has continued the theoretical investigation of microwave atmospheric interactions, in close coordination with personnel at the Naval Research Laboratory and elsewhere. The basic investigation concerns the propagation and absorption of microwaves above the breakdown threshold in the atmosphere with the self consistent breakdown plasma. Typical hydrodynamic calculations show that an ionization front is rapidly formed which moves toward the microwave source and consequently decouples the microwaves from the original ionization region. By focusing the microwaves or using a reflector, ionization can be confined to localized regions where the microwave strength is high enough to cause breakdown even though the incoming microwaves are below threshold.
