A new single surface integral equation is derived for light scattering by circular dielectric cylinders. Without adopting the concept of equivalent electric or magnetic surface currents, our formulation is directly derived from coupled-surface integral equations by the property of commutative matrices of Green functions. Further development by such matrix equations leads to only one unknown fun...

In this paper, we present four different formulations for the analysis of electromagnetic scattering from arbitrarily shaped three-dimensional (3-D) homogeneous dielectric body in the frequency domain. The four integral equations treated here are the electric field integral equation (EFIE), the magnetic field integral equation (MFIE), the combined field integral equation (CFIE), and the PMCHW (...

In this paper a solution of combined field integral equation (CFIE) for electromagnetic scattering by an arbitrary shaped dielectric object is studied. We derive a novel CFIE formulation in which the electric and magnetic field integral equations (EFIE and MFIE) are combined in the usual manner outside the object. Inside the object CFIE is composed by changing the roles of EFIE and MFIE. In add...

We investigate the use of edge element basis vectors in an integral equation solution for three-dimensional geophysical electromagnetic modelling. Expansion of the total electric field within the region of anomalous conductivity in terms of these basis vectors gives a bilinear variation of each component of the field within a cell in the two directions perpendicular to the component (and so a d...

A new higher-order method of moment (MoM) technique is presented for volume-surface integral equations (VSIE) for electromagnetic modeling of composite metallic and dielectric objects. The higher-order MoM scheme comprises higher-order hierarchical Legendre basis functions and an accurate representation of the object by higher-order curvilinear elements. Due to the orthogonal nature of the basi...

In this paper, we investigate various methods for solving a time-domain electric field integral equation (TD-EFIE) and a timedomain magnetic field integral equation (TD-MFIE) for analyzing the transient electromagnetic response from three-dimensional (3-D) dielectric bodies. The solution method in this paper is based on the method of moments (MoM) that involves separate spatial and temporal tes...

In this paper we present an electric field volume integral equation approach to simulate surface plasmon propagation along metal/dielectric interfaces. Metallic objects embedded in homogeneous dielectric media are considered. Starting point is a so-called weak-form of the electric field integral equation. This form is discretized on a uniform tensorproduct grid resulting in a system matrix whos...
