Scattering of a Shielded Surface Wave in a Coaxial Waveguide by a Wall Impedance Discontinuity (Correspondence)

The Wiener-Hopf technique is used to calculate the transmission and reflection coefficients of a shielded surface wave in a coaxial waveguide with inductively reactive inner surface and perfectly conducting outer surface and characterized by an abrupt wall reactance discontinuity. A lumped parameter equivalent circuit is derived for the discontinuity.
