Karazin popup.description2 The purpose of the work is to study the electrodynamic characteristics of photonic crystal structures with defects affecting the interaction efficiency with linear electron beams in terahertz devices. The development of a nonlinear theory of self-consistent beam-wave interaction in systems containing electrodynamic systems based on photonic crystal structures. The dispersion diagrams of the photonic crystal structure and the electric field spatial distribution in the waveguide channel for various values of the system parameters were obtained. The basic equations of the self-consistent theory of beam-wave interaction of linear electronic beams with fields of the photonic crystal structures modes are obtained. The passing of terahertz radiation through a one-dimensional photonic crystal with a defect layer containing the superconductor is considered. The existence of localized modes in the defect has been proved, which lead to resonant amplification of the transmittance. Product Description popup.authors Є. Одаренко А. Звягінцев В. Мізернік В.
