Multi-Beam MTM High Power Microwave Source

Abstract

Microwave sources transform the kinetic energy of an electron beam into microwaves through the interaction of the electrons with a periodic slow wave structure (SWS). A metamaterial (MTM) waveguide is proposed for use in a microwave oscillator instead of a SWS, which have been used for a long time to generate high power. MTMs have interesting properties such as negative refractive index, low group velocity, below cut-off propagation, among others.
