Metamaterial Cathodes in Multi-Cavity Magnetrons

Abstract:

The paper presents results of computer experiments performed for research to enhance operational parameters of multicavity magnetrons through using the metal-thin-wire MTW and the metal-split-ring MSR metamaterial structures as a cold non-thermionic cathode. It is demonstrated by particle-in-cell PIC simulations of a generic 10-vane non-relativistic ultra-high frequency UHF magnetron that the output microwave power and the start-up time of this magnetron are improved by replacing either a solid or a transparent cathode by a bulk MTW metamaterial structure formed by an array of individual wires directed parallel to the axis of the magnetron rodded cathode.
