Parallelization of Rigorous Light Scattering Simulation Algorithms for Nanostructured Surfaces

Scattered light measuring processes can be investigated and designed using numerical simulation. In the case of nanostructured surfaces new rigorous procedures are necessary for the computation of the scattered light. Existing approaches are not suitable because of the high computation efforts. For example, the discrete dipole approximation leads to systems with millions of coupled linear equations, which are solvable only by time consuming calculations. The paper investigates a procedure, which decouples the equations and calculates the developed subsystems in parallel on different computers.
