We report the experimental characterization of multimode networks. DUT
reference plane waveguides support two fundamental modes. A multimode
TRL calibration is used to derive multimode S parameters. Quasi-TEM a
nd first-wave simulation results are in good agreement with measuremen
ts. The present work outlines an interesting feature of the multimode
TRL calibration procedure. (C) 1997 John Wiley & Sons, Inc.
