Abstract
A virtual cathode is formed in a cavity, if the injection current from the diode exceeds the critical current. The propagation properties of the forwa rd current beyond the virtual cathode are investigated. It is shown that th e forward current increases significantly as the diode gap distance L-CA in creases, although the injection current from the diode decreases drasticall y. Experimental data agree well with theoretical results obtained analytica lly. (C) 2001 American Institute of Physics.
