Microwave undulators have great potential to be used in short‐wavelength free‐electron lasers. In this paper, the properties of a corrugated waveguide and its performance as an undulator cavity for a UK X‐ray free‐electron laser were systematically studied. The equations presented in this paper allow a fast estimation of the dimensions of the corrugated waveguide. An undulator cavity operating at 36 GHz designed for the HE 11 and HE 12 modes was investigated and the performance of both modes compared.
