Quasi-TEM analysis of multiconductor transmission lines embedded in lossy bianisotropic media

In this paper the propagation in a waveguide consisting of a number of conductors embedded in a lossy bianisotropic medium is investigated at low frequencies in the quasi-TEM regime. It is carefully shown that in this quasi-TEM regime Maxwell's equations reduce to a coupled set of generalised transmission lines describing the propagation of voltage and current wages along the conductors. In the second part of this paper some properties for these generalised transmission lines are discussed when the bianisotropic materials are reciprocal or lossless.
