A Sparse Discretization for Integral Equation Formulations of High Frequency Scattering Problems
We consider two-dimensional scattering problems, formulated as an integral equation defined on the boundary of the scattering obstacle. The oscillatory nature of high-frequency scattering problems necessitates a large number of unknowns in classical boundary element methods. In addition, the corresponding discretization matrix of the integral equation is dense. We formulate a boundary element m...

متن کاملWell-conditioned boundary integral equation formulations for the solution of high-frequency electromagnetic scattering problems
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 ...
متن کاملA new high-order high-frequency integral equation method for the solution of scattering problems II: Multiple-scattering configurations
We present a high-order, high-frequency solver for the numerical solution of problems of electromagnetic or acoustic scattering by bounded surfaces. This algorithm, which combines the use of an ansatz for the unknown density in a boundary integral formulation with an extension of the ideas of the method of stationary phase, can resolve problems of arbitrarily high-frequencies with a prescribed ...
متن کاملA High-frequency Integral Equation Method for Solving Em Scattering Problems Involving Large Faceted Bodies
A novel technique for efficient and rigorous solution of the problem of electromagnetic scattering from 2D-faceted conducting bodies is introduced in this paper. The Electric Field Integral Equation (EFIE) is solved by resorting to analytically-derived basis functions that preserve some of the desired features of the high-frequency solutions. The sub-domains in which the basis functions are def...
