Abstract : Microwave energy is coupled into an elongate waveguide having a rectangular main cavity with a lateral branch forming a T section. An intense beam of electrons is generated in the rectangular cavity as a particular location relative to the T to reflect incident microwave energy and produce a standing wave. Quarter wavelength spacing of the beam from the T positions either a wave node or antinode at the T. Preferably, in its 'open' state, accumulated microwave energy is released as a high power output pulse by establishing an antinode at the T. Alternatively, a node at the T produces a normally 'closed' state. In all arrangements, the beam of electrons, which traverses the central portion of the narrow dimension of the rectangular cavity in a direction parallel to the electrical field of its microwave energy, is of sufficient electron density to assure the desired reflection and produce the interference pattern.
