Full-wave analysis of three-dimensional electric field distributions in periodic coplanar waveguides

The full-wave spectral-domain technique is developed to investigate the characteristics of periodically nonuniform coplanar waveguides (CPW). The Floquet's theorem and the Galerkin's method in the Fourier-spectral domain by using a set of appropriate basis functions are used to obtain the numerical results for the three-dimensional electric field distributions in the periodic coplanar waveguides.
