摘要：
In Extended Interaction Klystrons (EIK), multiple interaction gaps within one cavity is used to increase the impedance of the cavity eigenmode, decrease the voltage between each gap, and enhance the power capability of the cavity. It is significant to project numerical simulation method used in the analysis of cavities with multiple coupled gaps. In this paper, using the finite element method, a simulator named High Frequency Circuit Simulator for Cavity (HFCS-C) was developed and used for design and analysis of multi-gap coupled cavity. To validate HFCS-C, numerical results for a double-gap coupled cavity structure are compared with HFSS in detail.
