A new full-wave modal technique for fast modeling of isotropic/anisotropic asymmetric CPW

In this paper, an original dispersive numerical modal approach combining accuracy and speediness is presented as promising tool for fast analysis of asymmetric coplanar waveguide on isotropic/anisotropic substrates. For this purpose, a quasi-symmetric model was introduced using C and π mode trial functions along with the formalism of operators to efficiently study the dispersion effect of coplanar structures. Comparisons with published and asymmetric model data are presented to further confirm the adequate choice of trial functions used in this quasisymmetric approach.
