High-frequency, high-power microwave radiations by a virtual cathode oscillator have been observed using the “point pinch diode” which can produce a high electron beam density. The peak power of microwave pulses is typically 350 MW in the frequency region of 20-22 GHz. The radiation frequency increases almost linearly from 20 to 35 GHz with decreasing anode-cathode gap spacing. The mechanism for microwave emission is ascribed to the oscillation of the virtual cathode.
