Mutual impedance between probes in a circular waveguide

Abstract

The general formulas of mutual impedance between two probes arbitrarily located in a circular waveguide are derived by a dyadic Green's function (DGF) and reaction concept. The waveguide is semi-infinite. The reflection coefficient at the terminal plan is Gamma . The lengths, feeding points and orientations of the two probes in the waveguide are all arbitrary. As examples, expressions of mutual impedance for three specific cases are given and discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
