A hybrid equivalent dipole moment and adaptive modified characteristic basis function method for electromagnetic scattering by multilayered dielectric bodies

Abstract

In this article, the equivalent dipole moment (EDM) method is extended and applied to analyze the electromagnetic scattering of multilayered dielectric bodies. Besides the advantage of reducing the computation time, the proposed EDM method makes it unnecessary to treat the boundary condition on the surface or the interface of the multilayered dielectric body. However, the EDM method is incapable of saving memory. In this case, the adaptive modified characteristic basis function (AMCBF) method is introduced and combined with the EDM method. Numerical results are given to demonstrate the merits of this EDM-AMCBF method. © 2009 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2009.
