Angular and Spectral Distributions of the Broadband Radiation of a Photoemission Source

Аннотация

Angular dependence of the electric field of electromagnetic wave generated by a rectangular photoemission source with the given surface density of dipole moment is determined. The dipole emission is initiated by the wave that propagates along the surface at a superluminal phase velocity. The spectral distribution of the radiation is determined, and the angular distribution of the radiation energy is calculated.
