    • Error control of multiple-precision MLFMA 

      Kalfa, M.; Ergül, Ö.; Ertürk, V. B. (Institute of Electrical and Electronics Engineers, 2018)
      We introduce and demonstrate a new error control scheme for the computation of far-zone interactions in the multilevel fast multipole algorithm when implemented within a multiple-precision arithmetic framework. The proposed ...
    • Fast multipole method for the solution of electromagnetic scattering problems 

      Ergül, Özgür Salih (Bilkent University, 2003)
      The fast multipole method (FMM) is investigated in detail for the solution of electromagnetic scattering problems involving arbitrarily shaped three-dimensional conducting surfaces. This method is known to reduce the ...
    • Iterative near-field preconditioner for the multilevel fast multipole algorithm 

      Gürel, L.; Malas, T. (Society for Industrial and Applied Mathematics, 2010-07-06)
      For iterative solutions of large and difficult integral-equation problems in computational electromagnetics using the multilevel fast multipole algorithm (MLFMA), preconditioners are usually built from the available sparse ...
    • Solution of radiation problems using the fast multipole method 

      Gürel, L.; Şendur, İ. K. (IEEE (Institute of Electrical and Electronics Engineers), 1997)
      Electromagnetic radiation problems involving electrically large radiators and reflectors are solved using the fast multipole method (FMM). The FMM enables the solution of large problems with existing computational resources ...
