ALEXANDRIA, Va., July 14 -- United States Patent no. 12,683,263, issued on July 14, was assigned to Doty Scientific Inc. (Columbia, S.C.).

"Bidirectional overmoded THz coupler" was invented by F David Doty (Columbia, S.C.) and Glenn N Doty (Columbia, S.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A low-loss bidirectional HE11 coupler is disclosed with substantially higher directivity than prior HE11 THz couplers for overmoded waveguides operating in a frequency band centered about f0, where f0 is between 0.03 to 1.5 THz, with mid-band free-space wavelength Lambda0. The coupler comprises a main hollow-metal waveguide, aligned along the z axis, of inner radius r1, where r1 is greater than 2Lambda0, a firs...
