Power absorbing termination for a waveguide transmission line

摘要

A power absorbing termination for a waveguide transmission line comprised of a waveguide section containing a fluid carrying dielectric taper which is inclined relative to the waveguide axis so that the point end of the taper lies against the guidewall of the waveguide section. Fluid in the dielectric taper is preferably circulated around a center planar divider extended down the taper's axis; alternatively, fluid is circulated through the taper by inducing a spiral flow of fluid in the taper hollow.
