Undulators as the sources of high‐brilliance synchrotron radiation are of widespread interest in new generations of light sources and free‐electron lasers. Microwave propagation in a plasma‐filled elliptical waveguide can be studied as a standard short‐period undulator. This structure as a lucrative insertion device can be installed in the storage ring of third‐ and fourth‐generation light sources to produce high‐energy and high‐brilliance synchrotron radiation. In this article, the propagation of the transverse electric modes in a plasma‐filled waveguide with an elliptical cross‐section is investigated, and the field components, the cut‐off frequencies and the electron beam trajectory are calculated. With due consideration of the electron beam dynamics and in order to achieve a standard short‐period undulator, parameters such as the dimensions of the waveguide elliptical cross‐section, the microwave frequency and the plasma density are calculated.
