We present a low-frequency fast multipole method for the solution of three-dimensional electromagnetic problems involving small objects and their dense discretizations with respect to wavelength. The diagonalization of the Green's function is stabilized using a multiple-precision arithmetic (MPA) for accurate and efficient computations of subwavelength interactions. MPA provides a direct remedy for the low-frequency breakdown of the standard diagonalization based on plane waves, and it enables straightforward implementations for low-frequency problems.

Fast-Multipole-Method Solutions of New Potential Integral Equations Gür, Uğur Meriç; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2017-09-27) A recently introduced potential integral equations for stable analysis of low-frequency problems involving dense discretizations with respect to wavelength are solved by using the fast multipole method (FMM). Two different implementations of FMM based on multipoles and an approximate diagonalization employing scaled plane waves are developed and used for rigorous solutions of low-frequency problems. Numerical results on canonical problems demonstrate excellent stability and solution capabilities of both imp...
PIE-MLFMA Implementation for Solving Complex Subwavelength Electromagnetic Problems Gur, Ugur Meric; Cetin, Isa Can; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2018-08-10) We present stable solutions of low-frequency electromagnetic problems involving small objects and their dense discretizations with respect to wavelength. Recently developed potential integral equations (PIEs), which are based on the boundary conditions for the magnetic vector potential and the electric scalar potential, are used to formulate complex problems. A multilevel fast multipole algorithm (MLFMA) based on scaled plane waves for stable computations of short-distance interactions is further employed t...
An Integral-Equation-Based Method for Efficient and Accurate Solutions of Scattering Problems with Highly Nonuniform Discretizations Khalichi, Bahram; Ergül, Özgür Salih; Erturk, Vakur B. (2021-01-01) © 2021 IEEE.We present a full-wave electromagnetic solver for analyzing multiscale scattering problems with highly nonuniform discretizations. The developed solver employs an elegant combination of potential integral equations (PIEs) with the magnetic-field integral equation (MFIE) to improve the iterative convergence properties of matrix equations obtained via method of moments, especially derived from highly nonuniform discretizations for which PIEs suffer from ill conditioning. A mixed-form multilevel fa...
Comparison of Integral-Equation Formulations for the Fast and Accurate Solution of Scattering Problems Involving Dielectric Objects with the Multilevel Fast Multipole Algorithm Ergül, Özgür Salih (2009-01-01) We consider fast and accurate solutions of scattering problems involving increasingly large dielectric objects formulated by surface integral equations. We compare various formulations when the objects are discretized with Rao-Wilton-Glisson functions, and the resulting matrix equations are solved iteratively by employing the multilevel fast multipole algorithm (MLFMA). For large problems, we show that a combined-field formulation, namely, the electric and magnetic current combined-field integral equation (...
Accurate solutions of scattering problems involving low-contrast dielectric objects with surface integral equations Ergül, Özgür Salih (2007-11-16) We present the stabilization of the surface integral equationsfor accurate solutions of scattering problems involvinglow-contrast dielectric objects. Unlike volume formulations,conventional surface formulations fail to provide accurateresults for the scatteredfields when the contrast of theobject is small. Therefore, surface formulations are requiredto be stabilized by extracting the nonradiating parts of theequivalent currents. In addition to previous strategies forthe stabilization, we introduce a n...
