Фотонно-кристаллический диафрагмированный волновод – электродинамическая система для усилителя терагерцового диапазона

Abstract

Characteristics of the beam-wave interaction of the sheet electron beam with eigenmodes fields of the photonic crystal iris waveguide are considered. Analysis is carried out on the base of nonlinear multidimensional theory of the O-type electron devices with non-resonant electrodynamic systems. Physical reasons of the efficiency enhancement in the beam-wave system are discussed. It is shown that the application of the photonic crystal structures in the terahertz electron devices is perspective.
