A new generalised approach for the fullwave analysis of shielded printedcircuit transmission lines with finite metallisation thickness is presented. A rigorous formulation for the electric field vector is employed, representing the hybrid electromagnetic field in layers of multidielectric media. The dyadic Green's function of the electric kind is derived as a kernel of the vector integral representations for the electric field. Based on the method of overlapping regions, the approach can be applied to the characterisation of a large class of planar waveguiding structures to yield a set of linear algebraic equations of the second kind with a compact matrix operator. Numerical examples are shown for single and coupled shielded planar transmission lines illustrating application of the method. The technique described allows obtaining accurate and mathematically correct solutions of planar waveguide eigenvalue problems.
