Abstract :
A Vlasov mode converter for a 94 GHz whispering gallery mode gyrotron, consisting of a Vlasov-type helically-cut launcher and two curved-mirror reflectors, is proposed in this paper. Applying the geometric optics theory and the vector diffraction theory, a numerical simulation code of the quasi-optical converter system is programmed. Simulation results indicate that the TE12,2 whispering gallery mode inside the 94 GHz gyrotron is converted into a highly Gaussian-like beam at the output window.
