Full-wave spectral Green's function integral-equation calculation of coplanar ferroelectric thin-film transmission structures

Here, a full-wave spectral-domain integral-equation technique is employed t o study planar guiding structures loaded with thin-film ferroelectric mater ial The Green's function is used in the isotropic format to treat those eas es where it is appropriate to evaluate the slowing behavior on the propagat ion constant. Specific coplanar structures with very low dispersion, amenab le to static potential biasing from the surface, are examined. Numerical re sults are obtained showing the effects of the layer thicknesses of the thin films and ferroelectric permittivities on the propagation constant.* (C) 2 000 John Wiley & Sons, Inc.
