Mathematical modeling of a low-voltage multibeam klystron of millimeter range

The purpose of this work is to determine the efficiency of low-voltage multibeam klystrons in the Ka-frequency range, using an electron-optical klystron-analog system operating in the Кu-range. Methods. The natural frequencies and main dimensions of the resonators were found by solving the Maxwell equations by the finite difference method in the time domain (FDTD) with a rectangular spatio-temporal partition grid.
