Abstract

Abstract

A metallic metamaterial high power microwave (HPM) mode converter which converts cylindrical TEM mode to TE11 mode is presented. Metallic sector grid elements are periodically arranged both in the azimuthal and longitudinal directions to gain high refractive index to act as phase shifter in the convertor. The mode converter is simulated by 3D commercial electromagnetic simulation software CST Microwave Studio. Simulation results show that the converter has high conversion efficiency with a relative bandwidth of about 4%. The radiation antenna with a metamaterial mode converter is simulated. The mode convertor is simulated combined with an L-band MILO tube using a particle-in-cell software, and a TE11 mode HPM is obtained in the outlet of the tube.
