Abstract:
1. A microwave pulse compressor having an operating frequency, the microwave pulse compressor comprising an elongated waveguide resonator having waveguide guide walls and opposed shorting end walls, wherein a distance between said shorting end walls defines a length of the waveguide resonator, and wherein the length of said waveguide resonator is chosen based on the following criteria: said waveguide resonator being oversized in that cross-sectional dimensions thereof are larger than required to propagate the fundamental mode only, a resonator input for coupling microwave power into said waveguide resonator during a fill time, said resonator input being located so as to couple said microwave power to said waveguide resonator approximately at a mid-plane between the opposed shorting end walls, at least one fast-action shorting switch positioned in front of at least one of the shorting end walls and defining a switch-out end of said waveguide resonator, wherein activation of said at least one fast-action shorting switch shifts maximum electric and magnetic fields of the fundamental mode within the waveguide resonator, and two output transmission lines coupled to opposite sides of said waveguide resonator so as to couple said microwave energy stored in the waveguide resonator during the fill time out of the waveguide resonator in a compressed pulse of microwave power when said at least one fast-action shorting switch is activated.
