Numerical calculation of the electrodynamic characteristics of the diode oscillator with photonic crystal resonator

Benedik Andrej Ivanovich, Saratov State University

Design of a diode oscillator with a field­emission cathode placed in a photonic crystal (PC) resonator is described. Results of numerical calculation of basic electrodynamic parameters of the PC resonator are presented. The 3D electrodynamic simulation by using the modern software package HFSS shows that varying the design of the energy output allows control of the loaded Q­factor in a wide range. Selection of the optimal value of the loaded Q­factor provides rather high output power and efficiency for reasonable values of the field­emission cathode current density.
