Abstract
A new quasistatic analysis of a coplanar waveguiding structure with multidielectric layers is presented, using a hybrid approach that combines the Galerkin finite-element method and the conformal-mapping technique. In the study, Wen´s (1969) mapping function is adopted, which not only transforms the infinity problem domain into a finite region, but also overcomes the field singularity difficulty around the strip edges. Numerical results for effective dielectric constants, characteristic impedances, charge distributions and field distributions for various multilayer coplanar line structures are presented and the magnetic wall assumption over the slot is also investigated
