ABSTRACT:
A plasma-filled waveguide acts as a dispersive element for pulse compression or power multiplication of a frequency chirped microwave signal. In one embodiment, the frequency of the source is chirped near a plasma resonance while the plasma waveguide is held contant in time. In a second embodiment, the source frequency is held fixed while the plasma filled waveguide parameters are varied in time in the vicinity of a plasma resonance.
