An exact analysis of coplanar waveguides and strip lines with full-wave method

Abstract

An new formula of coplanar waveguide and strip lines with full-wave method based on Fourier transform technique with modified perfectly matching boundary(MPMB). In the formula, the singularity are accurately considered. All the infinite integrals are calculated by a residue method, in which they are transformed into infinite summations with very fast convergence. The introduced MPMB ensure that the computing accuracy is very high. The proposed method will give a very accuracy and fast convergent solution. This method is also suitable for all the coplanar waveguides and strip lines with lossy substructure.
