ABSTRACT:
In a selective directional coupler composed of two outer waveguides, the outer waveguides are coupled together by an intermediate waveguide disposed between the two outer waveguides, the intermediate guide being constructed and positioned such that at a selected coupling frequency its coupling mode is in phase synchronism with the transmission modes in the two outer waveguides.
