MICROWAVE GENERATING DEVICE WITH OSCILLATING VIRTUAL CATHODE

摘要

The invention concerns a microwave generating device comprising a diode (4, 2) consisting of an anode (4) and a cathode (2) and adapted to create a virtual cathode (6) by accumulation of electrons in a circular waveguide (5) capable of propagating a microwave emitted by oscillation of the virtual cathode (6). The invention is characterized in that it comprises a first reflector (8) transparent to electrons and reflecting the microwave and located in the waveguide (5) such that the virtual cathode (6) is positioned between the anode (4) and the first reflector (8). The invention is applicable to power generation in the microwave domain.
