    Abstract: A device for generating microwaves with an oscillating virtual cathode includes a cathode, and a thin anode positioned at an inlet of a cylindrical waveguide (5). The waveguide includes at least one first open reflector and one last open reflector that are transparent to electrons and capable of reflecting a microwave created by at least one virtual cathode generated in the waveguide. A plurality of open reflectors are between the first and last open reflector, such that a designated reflector of the plurality of open reflectors has a radius R(i−1) less than or equal to a radius Ri of an immediately preceding reflector and the last open reflector has a radius RN less than a radius R1 of the first open reflector.

    Abstract: A reflecting electron tube for producing high-power, high-frequency, monoomatic microwave pulses includes an anode which produces little or no ion flux when struck by electrons emitted from a cathode, and requires no applied, external magnetic field. An anode support holding the anode and a cathode shank which supports the cathode are positioned within a vacuum chamber such that the anode is closely spaced from the cathode. The anode support is connected to a pulsed high-voltage supply located external to the chamber. The anode is formed from a material which does not produce a significant amount of ion flux but does permit electrons emitted from the cathode to oscillate through the anode. Electrons oscillating in phase bunch together within the potential well of the system and emit microwave radiation.
