Efficient andAccurate Consideration ofOhmicLosses inWaveguide Diplexers andMultiplexers

Theaccurate consideration ofallohmiclosses p (5) effects inwaveguide manifold diplexers andmultiplexers port isrigorously studied inthispaper. Forsuchpurposes, a port (4) full-wave CAD toolbasedexclusively onmodalmethodsis \ originally proposed. Proceeding inthisveryefficient way, losses areprecisely considered inallcommon components ofsuchcomplex devices, i.e. planar junctions, uniform lines andmulti-port circuits implemented inwaveguide technology. b Forverification purposes, wehavesuccessfully compared our results foramagic-T junction andamanifold diplexer with experimental andnumerical results.pot ) IndexTerms-Losses, Waveguide components, Multiport por circuits, Diplexers andmultiplexers.
