Abstract :
A self-consistent mathematical model of the spatial-harmonic magnetron (SHM), with cold secondary-emission cathode is proposed for investigating steady-state processes. Characteristic features of modeling space charge effects, secondary emission, and nonlinear electron-wave interaction are described. Illustrative examples of simulations are given in order to show peculiarities of the operation of the SHM as compared to conventional magnetrons. Multi-stable states of the magnetron are described. Results of simulations are compared with experimental data for an 8-mm-wave magnetron
