Abstract
The article presents the results of numerical simulation of a new design of a double-gap photonic crystal resonator (DGPBG) for use in a multi-beam low-voltage Ku band klystron. A design feature is the use of a photonic crystal lattice and a dielectric substrate with strip resonant elements in the resonator. The main electrodynamic parameters were investigated for the main anti-phase and higher in-phase modes of oscillations. The spectrum of resonant frequencies of the resonator is analyzed in the range from 10 to 21 GHz. The electronic parameters were investigated in the range of accelerating voltages from 2.5 to 7.5 kV. Practical recommendations have been developed for the selection of optimal parameters of resonator designs, which can be used in the development of miniature multi-beam klystron-type devices operating as amplifiers and generators.
