Abstract
A high power absorbing waveguide termination for a microwave transmission line has a power receiving end with a waveguide input port, an oversize waveguide section, and a transforming waveguide section for connecting the waveguide input port to the oversize waveguide. A dielectric taper disposed in the oversize waveguide section has a fluid passage therethrough to allow fluid, most suitably water, to sweep the taper and absorb microwave power introduced into the oversized waveguide section. Fluid is suitably fed into and extracted from the dielectric taper via a manifold end block at the back end of the oversize waveguide section. The taper is inclined relative to the center axis of the oversize waveguide section so as to position the point end of the taper in a region of very low electric field strength for the oversize waveguide section's fundamental mode. A power monitoring probe is optionally provided at the input port of the waveguide termination.
