    • Enhancing the accuracy of the interpolations and anterpolations in MLFMA 

      Ergül, Özgür; Gürel, Levent (Institute of Electrical and Electronics Engineers, 2006)
      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 ...
    • Lebesgue constants on cantor type sets 

      Paksoy, Yaman (Bilkent University, 2020-09)
      The properties of compact subsets of the real line which are in the class of Bounded Lebesgue Constants (BLC) are investigated. Knowing that any such set must have 1-dimensional Lebesgue measure zero and nowhere density, ...
    • Optimal interpolation of translation operator in multilevel fast multipole algorithm 

      Ergül, Özgür; Gürel, Levent (Institute of Electrical and Electronics Engineers, 2006)
      Lagrange interpolation of the translation operator in the three-dimensional multilevel fast multipole algorithm (MLFMA) is revisited. Parameters of the interpolation, namely, the number of interpolation points and the ...
    • Two-step lagrange interpolation method for the multilevel fast multipole algorithm 

      Ergül, Z.; Bosch, I.; Gürel, Levent (Institute of Electrical and Electronics Engineers, 2009)
      We present a two-step Lagrange interpolation method for the efficient solution of large-scale electromagnetics problems with the multilevel fast multipole algorithm (MLFMA). Local interpolations are required during aggregation ...
