In this paper we analyse the computational aspects of a numerical method for solving the Electric Field Integral Equation (EFIE) for the analysis of the interaction of electromagnetic signals with thinwires structures. Our interest concerns with the design of an efficient parallel implementation of this numerical method which helps physicist to solve the Electric Field Integral Equation for ver...

The electric field enhancement associated with detailed structure within novel optical antenna nanostructures is modeled using the surface integral equation technique in the context of surface-enhanced Raman scattering (SERS). The antennae comprise random arrays of vertically aligned, multiwalled carbon nanotubes dressed with highly granular Ag. Different types of "hot-spot" underpinning the SE...

We deal with the scattering phenomenon from an abruptly terminated asymmetrical slab waveguide for the case of transverse magnetic (TM) modes. The analysis uses both the integral equation method and the variational technique. The reflection coefficient of the dominant TM guided mode and the far-field radiation pattern are computed, and the discontinuity of the electric field distribution on the...

Electromagnetic scattering is considered from finite and electrically large perfectly conducting rough surfaces. Three solution approaches are considered. The first two are based on a multi-level fast-multipole algorithm (MLFMA) formulation. In one MLFMA approach the rough surface resides in free space and is terminated by a resistive taper. In the second MLFMA approach the rough surface is ter...

We present several versions of Regularized Combined Field Integral Equation (CFIER) formulations for the solution of three dimensional frequency domain electromagnetic scattering problems with Perfectly Electric Conducting (PEC) boundary conditions. Just as in the Combined Field Integral Equations (CFIE), we seek the scattered fields in the form of a combined magnetic and electric dipole layer ...

This paper deals with the problem of diffraction radiation from an electric point charge that moves, at a constant speed, through a circular aperture in a plane screen. The screen is assumed to be electrically perfectly conducting. The problem is reduced to the solution of an integral equation for an unknown field function in the aperture. Low-frequency solutions as well as high-frequency solut...

in this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (er) fluid core is investigated. the rectangular plate is covered an er fluid core and a constraining layer to improve the stability of the system. the two outer layers of the sandwich structure are elastic. the viscoelastic materials express the middle layer behavior under electric field and small st...

This paper presents the adaptive integral method (AIM) utilized to solve scattering problem of mixed dielectric/conducting objects. The scattering problem is formulated using the Poggio-MillerChang-Harrington-Wu-Tsai (PMCHWT) formulation and the electric field integral equation approach for the dielectric and conducting bodies, respectively. The integral equations solved using these approaches ...

When a composite is subjected to a constant applied electric, thermal, or stress field, the associated local fields exhibit strong spatial fluctuations. In this paper, we evaluate the distribution of the local electric field ~i.e., all moments of the field! for continuum ~off-lattice! models of random dielectric composites. The local electric field in the composite is calculated by solving the ...
