Numerical simulation and optimization of electromagnetic field of TE103 sing-mode cavity

We calculated numerically the distribution of the electromagnetic field in the TE103 sing-mode resonance cavity. A mathematical expression was deduced to describe the electromagnetic field distribution of the cavity based on the Maxwell Equation. The electromagnetic field distribution in the microwave resonance cavity was analyzed with the Ansoft software. The properties of the cavity were judged according to the distribution of the electromagnetic field and other relevant data. The simulation results show that there are three even electric field regions with the same size in the microwave resonance cavity without load and the cavity has a high quality when matched. The numerical simulation results are in accordance with the experimental results, which prove the correctness of the calculation and simulation and provide the evidence for designing the resonance cavity.
