Waveguide load having reflecting structure for diverting microwaves into absorbing fluid

DETAILED DESCRIPTION An object of the invention is to provide a waveguide calorimetric load for a wave with circular electric field.
A further object is to provide a load which will handle very high powers at very high frequencies.
A further object is to provide a compact, rugged load.
A further object is to provide a load which is well matched to its waveguide over a wide band of frequencies.
A further object is to provide a load which is easy to manufacture.
These objectives are realized by a load having a cylindrical window at the outside of the waveguide surrounded by a jacket of water.
Wave energy propagating down the guide is deflected outward through the window by a conical, metallic reflecting member coaxial with the circular waveguide.
