GENERATOR OF ELECTROMAGNETIC PULSES Russian patent published in 2015 - IPC H01J25/00 

FIELD: electricity.

SUBSTANCE: invention is referred to method of electromagnetic pulses (EMP) generation and may be used in pulse detection and ranging and pulsed filed testing of radio electronic equipment. The device includes photocathode and mesh anode with their operating surfaces made as surfaces of rotation bodies are connected to voltage source, pulse or pulse-periodic light source, converter converting radiation of the light source into spherically diverging wave of optical, ultraviolet or X-ray radiation, which radiation centre matches focus of the photocathode. The mesh anode is placed at equidistance from the photocathode, and operating surface of the photocathode is represented by nonsymmetrical cutout from paraboloid of rotation deformed by shifting its points from the peak and along radius of rotation in regard to radius of rotation. Additional distinctions may include the fact that nonsymmetrical cutout from paraboloid of rotation may be made as a circular or oval cylinder or rectangular prism. The converter may be made as parabolic mirror with metal or dielectric multilayer coating or as flat target of spherical, conical or flat shape.

EFFECT: improved directivity and increased intensity of the generated electromagnetic emission, which allows expanding its scope of application in radar detecting and ranging and tests methods for pulsed electromagnetic effects.
