ABSTRACT:
A hollow waveguide has a rectangular or square internal cross-section, with all internal surfaces coated with a reflecting metal such as silver. One pair of opposing surfaces is dielectric overcoated of a thickness less than half the quarter wave thickness, while the other pair of opposing surfaces is dielectric overcoated with a different material and has a thickness which is an integral multiple of the quarter wave thickness. ThF.sub.4, ZnSe, and Ge are suitable materials.
