Abstract


In this paper, concept of the strong Finite Element Method (FEM)formulation is explained first. A brief review of strong basis functions that are used forquasi-static analysis of transmission lines with piecewise homogeneous anisotropicmedium is presented next. As numerical examples, effective relative permittivities ofsquare coaxial lines with two anisotropic layers or one isotropic and one anisotropiclayer are calculated by using the Galerkin variant of the strong FEM formulation. It isshown that in the case of the half-filled line, effective relative permittivity is practicallyequal to the value obtained by a simple formula.
