A Vlasov mode converter for a TE02 mode gyrotron, consisting of a Vlasov stepped-cut launcher, an elliptical reflector and a parabolic reflector, is proposed in this paper. Applying the geometric optics approximation and the vector diffraction theory, a numerical simulation code of the quasi-optical converter system is programmed. Simulation results indicate that the TE02 mode inside the 94GHz gyrotron...
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...
A quasi-optical mode converter for a TE02 mode gyrotron is designed. The mode converter consists of a launcher, an elliptical reflector and a parabolic reflector. Based on the vector diffraction theory, the mode converter is ananlyzed by using using numerical calculation and three-dimensional electromagnetic code. The simulation results show that the good Gaussian mode is converted from the circular...
