A rigorous spectral domain-mode analysis of multilayered anisotropic asymmetric coupled structures in millimeter-wave band

This paper presents a rigorous millimeter-wave spectral domain approach for an efficient analysis of asymmetric coupled microstrip-type structures on anisotropic multilayered substrates. A suitable choice of basis functions with metallic edge effects is proposed via the Galerkin's procedure. This technique leads to faster and accurate characterization with simulated results successfully compared with published data.
