We present an approximate diagonalization of the Green's function that is stable at arbitrarily short distances with respect to wavelength. The diagonalization is based on scaled spherical functions and plane waves, where a scaling factor is used to stabilize special functions with small arguments. Optimization of the scaling factor leads to accurate diagonalizations, which can be used to implement the multilevel fast multipole algorithm for low-frequency problems.

Efficient solution of the electric-field integral equation using the iterative LSQR algorithm Ergül, Özgür Salih (Institute of Electrical and Electronics Engineers (IEEE), 2008-01-01) In this letter, we consider iterative solutions of the three-dimensional electromagnetic scattering problems formulated by surface integral equations. We show that solutions of the electric-field integral equation (EFIE) can be improved by employing an iterative least-squares QR (LSQR) algorithm. Compared to many other Krylov subspace methods, LSQR provides faster convergence and it becomes an alternative choice to the time-efficient no-restart generalized minimal residual (GMRES) algorithm that requires la...
Solutions of new potential integral equations using approximate stable diagonalization of the Green's function Gur, U.M.; Karaosmanoglu, B.; Ergül, Özgür Salih (2017-09-15) We present efficient and accurate solutions of scattering problems involving dense discretizations with respect to wavelength. Recently developed potential integral equations (PIEs) for stable solutions of low-frequency problems are used to formulate such challenging problems, where the electric current density and magnetic vector potential are defined as unknowns. For solving problems discretized with large numbers of unknowns, we further use an approximate diagonalization of the Green's function within th...
Efficient parallelization of the multilevel fast multipole algorithm for the solution of large-scale scattering problems Ergül, Özgür Salih (Institute of Electrical and Electronics Engineers (IEEE), 2008-08-01) We present fast and accurate solutions of large-scale scattering problems involving three-dimensional closed conductors with arbitrary shapes using the multilevel fast multipole algorithm (MLFMA). With an efficient parallelization of MLFMA, scattering problems that are discretized with tens of millions of unknowns are easily solved on a cluster of computers. We extensively investigate the parallelization of MLFMA, identify the bottlenecks, and provide remedial procedures to improve the efficiency of the imp...
Enhancing the accuracy of the interpolations and anterpolations in MLFMA Ergül, Özgür Salih (Institute of Electrical and Electronics Engineers (IEEE), 2006-01-01) We present an efficient technique to reduce the interpolation and anterpolation (transpose interpolation) errors in the aggregation and disaggregation processes of the multilevel fast multipole algorithm (MLFMA), which is based on the sampling of the radiated and incoming fields over all possible solid angles, i.e., all directions on the sphere. The fields sampled on the sphere are subject to various operations, such as interpolation, aggregation, translation, disaggregation, anterpolation, and integration....
Clarification of issues on the closed-form Green's functions in stratified media Aksun, MI; Dural Ünver, Mevlüde Gülbin (Institute of Electrical and Electronics Engineers (IEEE), 2005-11-01) The closed-form Green's functions (CFGF), derived for the vector and scalar potentials in planar multilayer media, have been revisited to clarify some issues and misunderstandings on the derivation of these Green's functions. In addition, the range of validity of these Green's functions is assessed with and without explicit evaluation of the surface wave contributions. As it is well-known, the derivation of the CFGF begins with the approximation of the spectral-domain Green's functions by complex exponentia...
