3D electromagnetic particle-in-cell simulations of a magnetron based on the realistic model

The objectives of the current study are to quantitatively analyze the electromagnetic interactions with the electrons drifting around the cathode in the process of the microwave generation in a magnetron by performing three-dimensional (3D) electromagnetic particle-in-cell (PIC) simulations with a realistic model of the internal of a magnetron. For this purpose we have developed a new 3D electromagnetic magnetron simulator with Cartesian coordinates. The magnetron efficiency obtained in the current simulation is approximately 73% which is very close the real magnetrons. The obtained power of the magnetron is 2.2 kW. These simulation facts guaranteed us that the newly developed simulator can correctly simulate a real magnetron function.
