The Application of Modern Electromagnetic Simulation Tools in the Experiment Teaching of Microwave Measurement

Regularly shaped microwave resonators have some analytical or semi-analytic formulas.However,as the complexity of the three-dimensional structure of the cavity of the microwave resonator increases,electromagnetic simulation tools increasingly show their capabilities and advantages.The correct use of these tools can greatly improve the speed of research and development,and to ensure the success rate of the project.In this paper,the mainstream commercial 3D electromagnetic simulation software was selected as the microwave digital simulation platform.A high frequency structure of single reentrant cavity in klystron was used as the experimental object,focus on training students the design,simulation and optimization of cavity,the physical model test,the main resonant cavity working parameters testing ability.The experimental teaching has good results.
