Pillbox-type windows transmitting power in the TM/sub 01/-mode of the circular waveguide

Abstract

The windows having power transmission in the TM/sub 01/-mode are known to be noncritical to the technological dispersion of the dielectric permittivity of the ceramic barrier. The origin of this property, which has not attracted attention of the researchers, is a reduced electric field in dielectric. Thus, it becomes possible to decrease the losses inside the ceramic and to increase the power capacity of the waveguide windows.
