Modeling of submillimetric magnetron on the first positive space harmonic of Π-mode oscilastions

The characteristics of a submillimetric-wave cold-cathode magnetron oscillator (SubMMO) operating on the first positive spatial π-mode oscillation harmonic are analytically modeled using the drift-orbital resonances and 3-D simulation. The results of this procedure are presented in the short report below. The distinguishing features of the nonlinear dynamics of electron-wave interaction between synchronous electrons and electromagnetic field. It is shown that using such a magnetron makes it possible generate pulses with HF-power magnitude varying from hundreds of mWs to tens of Watts.
