Simulation of 2-cavities resonator using CST / Zalilah Wahid

2-cavities resonator functioning with TE211 and TE311 mode is studied and presented in this project. The circular cavities are cascaded to obtain a second order bandpass response. Simulation is done to make comparisons between single and 2- cavities. The resonant frequencies are found at 5.65GHz and 7.36GHz Two probes are used in the simulation for wave excitation into and from the cavity. The best length of penetration probe is found to be 3mm. Probe is located at the maximum point of electric field. The work shows very close agreement between calculation and simulation. The simulation process is using CST process. The success of this project may lead to the usage of 2-cavities resonator in filter application.
