Cylindrical Gaussian-Hermite modes in rectangular waveguide resonators
Abstract
Approximate solutions to the wave equation inside a rectangular metallic waveguide has been obtained in terms of cylindrical Gaussian-Hermite functions. E mn pi modes propagate with negligible straight guide losses in the far-infrared region. A new type of low-loss optical resonator suitable for FEL (free-electron laser) operation at long wavelengths is presented here.
