【Abstract】 The varied coupled-cavity slow-wave structures (CCSWS) with modified coupled slots, taper drift tube and absorbed buttons were simulated by ANSYS software. Through the model analysis of single and multi-resonant cavities, the dispersion characteristic of CCSWS have been obtained,which are in agreement with experiments. An engineering computing method based on the combining ANSYS with a code of field-match method is present, which is valuable in engineering practice and convenient in TWT interaction design of complicated CCSWS.更多还原
