Abstract :
Combline directional couplers may be designed to have useful frequency-dependent transfer characteristics. The normal modes are optimised by a numerical technique to show that novel nonreflective filters and band-branching multiplexers may be achieved without the use of nonreciprocal components such as isolators and circulators.
