Title :
Approximate cutoff frequency of dielectric ridge waveguide, with application to travelling-wave masers
Abstract :
An approximate relation is obtained between the cutoff frequency and the geometry for dielectric ridge waveguide. This relation suggests that the cutoff frequency of rutile slab loaded rectangular waveguide will be substantially raised if the slab height does not exactly equal the waveguide height.
