Abstract

Abstract

A new idea of azimuthal partition to generate bifrequency high power microwave (HPM) is put forward in this paper. According to the operation mechanism of a conventional magnetically insulated transmission line oscillator (MILO), the interaction between electron flow and microwave is in the axial and radial direction, but not in the azimuthal direction. Therefore, establishing the azimuthal partition of cavitydepth in a conventional MILO, an L-band bifrequency MILO (BFMILO) is designed. The BFMILO is simulated and optimized by electromagnetic simulation. The particle simulation shows that when the electron beam voltage is 530 kV and the beam current is about 45.5 kA, a BFMILO can generates about 2.65 GW of HPM with two stable and separate frequencies-1.28 GHz and 1.50 GHz. The power effici
