A systematic spectral‐domain approach is described for obtaining higher order electromagnetic impedance boundary conditions for isotropic, longitudinally inhomogeneous, dielectric coatings on a polarization‐preserving impedance plane. Representative computational examples including single‐ and two‐layer inhomogeneous coatings are discussed to illustrate the accuracy of the proposed approach. ©1999 John Wiley & Sons, Inc.
