ABSTRACT

An important problem in the area of EM spectral domain analysis is the problem of using rigorous coupled wave analysis (RCWA) to determine the EM želds that result when an EM wave is incident on an inhomogeneous material object, that is, one whose dielectric permittivity and magnetic permeability parameters are functions of position. The RCWA algorithm, which was originally designed to study scattering from planar diffraction gratings [1-9], has been used to scattering from inhomogeneous objects when the inhomogeneous object was a phi-dependent circular cylinder [10-13], when the circular cylinder was an anisotropic permeability [14], when the object was a lossy biological material [15], when the object was an elliptical inhomogeneous cylinder [16,17], and when the scattering object was an inhomogeneous sphere [18,19]. Chapter 7 of this book and the žrst edition of this book [20] describes the RCWA method and its application to scattering from inhomogeneous objects.
