✦ Synopsis
A full-wa¨e integral-equation Green's function code in the spectral domain has been implemented using the finite Fourier transform consistent with complex media layered structures modeled in a cross-sectional region. The basis function set describing the strip currents or slot fields at the interface is able to handle asymmetric field distribution due to the intrinsic asymmetry caused by the material tensors. Theoretical issues related to determining the permitti¨ity or permeability tensors from the propagation constant are co¨ered in mathematical generality for rotated systems or arbitrary bias field orientations. A dispersion diagram for static electric-field-induced anisotropy in a ferroelectric loaded multilayered microstrip structure is pro¨ided, and a multistep computational process of de-embedding the permitti¨ity from the propagation constant ¨alues is demonstrated.
