The Scattering the TEM Mode at the Junction of Perfectly Conducting and Dielectric Loaded Grooved Coaxial Waveguides

Abstract

A rigorous Wiener-Hopf solution is derived for the analysis of coaxial waveguides with dielectric filled semi-infinite grooves in the inner and outer conductors. Such discontinuities can serve useful impedance matching functions in microwave circuits and may exhibit band stop filter characteristics.
