The magnetrons used in microwave ovens operate on the same frequency band as Wi-Fi equipment,
and the radiation they release can interfere with the operation of wireless networks. This paper presents
a multiphysics simulation of a magnetron using CST STUDIO SUITE®, with the aim of testing the
electrical, magnetic, thermal and mechanical characteristics of a low-interference magnetron design.
The simulation results are then compared to measurements made experimentally, and the two sets
of results are shown to be in good agreement.
