A convenient method is presented to obtain the dispersive characteristics of TM0n electromagnetic modes in the rectangular corrugation overmoded slow wave structure(SWS) by numerical simulation. The influence of average radius, period, amplitude of the SWS on the field distribution properties of the eigenmodes is investigated; the condition to maintain the surface and the volume waves is discussed; the reason that overmoded SWS can still operate in a single mode is analyzed. The results show that when the overmoded SWS structure parameters satisfy the condition and are matched with the annular beam voltage and radius, the total field of TM01 mode with longitudinal wavenumber of beamwave synchronous point locating near π mode is surface wave, and the system can operate in single TM01 mod
