Description
Summary:A formulation of the spectral domain technique (SDT) for the analysis of the general case of uniaxial/biaxial, electric/magnetic anisotropic multilayer planar structures is presented. As an illustration of the capabilities of this formulation it is applied to the analysis of shielded coplanar waveguide (CPW) structures. The dispersive properties of the fundamental and higher-order modes in various cases of electric/magnetic anisotropy as well as the induction electric and magnetic lines are calculated. Such results, and particularly the induction lines, may be used to predict the behavior of the structure studied as well as to point out its sensitive geometrical and electrical parameters. Some general rules which lead to a better understanding of the effect of anisotropy are discussed.< >
