Description
Summary:The quasi-TEM characteristic impedance of an imperfectly-conducting strip transmission line based on a full-wave analysis is investigated. The effect of the imperfect outer conductors of the stripline are accommodated via a dyadic Green's function satisfying surface impedance boundary conditions. The imperfect center conductor is accommodated through the use of a resistive sheet boundary condition and leads to an EFIE formulation for the quasi-TEM strip current. This center strip current subsequently allows computation of the quasi-TEM characteristic impedance. The effect that finite conductivity has on the quasi-TEM characteristic impedance is investigated. The importance of these results for use in future applications is discussed.
