electromagnetic scattering problems. Problems encountered in real-life applications
are often three dimensional and involve electrically large scatterers with
complicated geometries. When the MoM is employed for the solution of these
problems, the size of the resulting matrix equation is usually large. It is possible
to reduce the size of the system of equations by improving the geometry
modeling technique in the MoM algorithm. Another way of improving the efficiency
of the MoM is the fast multipole method (FMM). The FMM reduces the
computational complexity of the convensional MoM. The FMM has also lower
memory-requirement complexity than the MoM. This facilitates the solution
of larger problems on a given hardware in a shorter period of time. The combination
of the FMM and the higher-order geometry modeling techniques is
proposed for the efficient solution of large electromagnetic scattering problems
involving three-dimensional, arbitrarily shaped, conducting suriace scatterers.Sertel, KubilayM.S
