Below there are a photograph and the design of our high-frequency cylindrical EPR resonant cavity
This design is based on the specifications given in: M. Mola, S. Hill, P. Goy and M. Gross, Instrumentation for millimeter-wave magnetoelectrodynamic investigations of low-dimensional conductors and superconductors. Rev. Sci. Instrum. 71, 186 (2000)
Information about the resonant modes of the resonant cavity can be found in this file
