Klystron Double-Gap Resonator with Integration of CeSRR Elements into the Resonance System

The results of the research of a metamaterial klystron resonator in the form of an electric-type complementary split-ring resonator are reported. The electrodynamic parameters of the resonator and the electric field vectors in the resonator gap have been calculated by the finite element method in the frequency domain. The results of the calculation of the electronic parameters are given. The resonator can be used in miniature multi-beam klystron-type devices for various telecommunication and communication systems.
