TL;DR: In this article, the Lippmann-Schwinger equation for an inhomogeneous anisotropic medium was derived and the uniqueness and existence of a solution was shown and the regularity of the solution by means of integral equations.
Abstract: We investigate electromagnetic wave propagation in an inhomogeneous anisotropic medium. For the case of an orthotropic medium we derive the Lippmann-Schwinger equation, which is equivalent to a system of strongly singular integral equations. Uniqueness and existence of a solution is shown and we examine the regularity of the solution by means of integral equations. We prove the innnite Fr echet diierentiability of the scattered eld in its dependence on the refractive index of the anisotropic medium and we derive a characterization of the Fr echet derivatives as a solution of an anisotropic scattering problem.

TL;DR: The electromagnetic modeling of electronic packages is discussed, and a general-purpose Maxwell solver is presented for deriving equivalent circuits of various components of a package that can be inserted in a SPICE-type circuit simulation program to investigate the electrical performance of the package.
Abstract: The electromagnetic modeling of electronic packages is discussed, and a general-purpose Maxwell solver is presented for deriving equivalent circuits of various components of a package that can be inserted in a SPICE-type circuit simulation program to investigate the electrical performance of the package. The solver is based on the finite-difference-time-domain (FDTD) algorithm. Its usefulness is illustrated by applying it to a number of representative problems. >

TL;DR: In this paper, the equivalent dipolemoment (EDM) method is applied to compute the matrix elements of the MoM via solving the volume-surface integral equation (VSIE).
Abstract: In this letter, the equivalent dipole-moment (EDM) method is applied to compute the matrix elements of the method of moments (MoM) via solving the volume-surface integral equation (VSIE). Besides the advantage of reducing the calculation time significantly, this extended method is unnecessary to treat the boundary condition on the surface of dielectric body and easily constructed by using a simple procedure. The proposed approach can be applied if the distance between the source and the testing basis functions is beyond a threshold distance. Numerical results validate the efficiency and accuracy of the generated matrix elements, and the radar cross-section (RCS) has been verified.
