Multilevel Multipole -Free Fast Algorithm for Electromagnetic Scattering Problems in Layered Media

147 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2006.In addition, comparison of the memory usage and simulation time is presented for FIPWA and MF-FIPWA for moderate to large scale problems. Various alternate approaches to implementing MF-FIPWA are discussed in terms of how the fast algorithms set up translation matrices and where gains can be made. Finally, details of the advantages of using nonuniform sampling are provided. Results show 30% savings in memory usage and up to 20% savings in computing the matrix-vector product.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
