Microwave undulators can achieve smaller wiggler periods when compared with permanent magnet undulators. This work follows on the design of a microwave undulator composed of a corrugated waveguide operating at 36 GHz. Compatible end caps and coupling structures for the waveguide to form a complete cavity were studied and are presented in this paper. Their design is scalable for different operating frequencies and periods of the corrugated waveguide. A set of empirical equations, that allows the geometry to be determined analytically, were found from the post-processing of the FDTD simulation.
