Calculation of Parameters of Electromagnetic Radiation of Accelerated Electron Beams during Sliding Interaction with a Dielectric Surface

The parameters of electromagnetic radiation that should be generated during guiding of accelerated electrons (extended sliding interaction of accelerated electrons with a dielectric surface) pressed to the surface of a dielectric plate by an external electric field are calculated. The model of the effect (guiding) is proposed based on an analysis of the solution to the Hamilton equation for the motion of electrons in an external electric field and in the electrostatic field created by electrons deposited on the surface of a dielectric plate. Superposition of these fields leads to the fact that during guiding, electrons experience transverse vibrations relative to the surface of the plate, i.e., acquire lateral acceleration. And this, as is known, should lead to the generation of electromagnetic radiation, the frequency and intensity of which depend on the electron energy, similar to the radiation of undulators and wigglers. Calculations show that when electrons are guided, radiation should be generated depending on their energy. The maximum of its intensity is in the region from the IR to the radio frequency range.
