Simulation of microwave generation using the superluminal source

Summary form only given. The power produced by existing sources of microwave radiation falls off with decreasing wavelength. This is conditioned by the fact that as the wavelength is decreased the size of the region (where the energy which can be radiated is stored) decreases. To solve this problem a new concept is proposed for generating microwave radiation, based on the use of a superluminal source formed when electrons are emitted into vacuum from a medium and the emission front propagates along the surface with a speed greater than that of light. Hence the duration of radiation coincides with the time of electron layer formation, which evidently is defined by the electron Langmuir frequency.
