Abstract Microwave generation from a resonant cavity surrounding oscillating virtual cathode, which is produced by non-homogeneous electron beams, is studied experimentally. The microwave power is measured by using the crystal detector and frequencies are measured by using the heterodyne technique. A single microwave pulse contains two microwave signals with different frequencies, one peak power is 1.12MW at 5.03GHz and the other is 0.56MW at 5.24GHz, and their 3dB bandwidths are 18 and 25 MHz, respectively.
