Full-wave electromagnetic scattering at extremely large 2-D objects

Recent advances in the parallel multilevel fast multipole algorithm have paved the way for large-scale full-wave electromagnetic simulations. The introduction of the hierarchical partitioning technique and the use of an asynchronous parallel implementation have resulted in a scalable algorithm that runs efficiently, even on low-cost clusters. Presented is the accurate solution of the two-dimensional (2-D) transverse magnetic scattering at both a perfect electric conducting cylinder with a diameter of one million wavelengths and a dielectric cylinder with a diameter of half a million wavelengths.
