Abstrakt

We compare the discrete dipole approximation (DDA) and the finite difference time domain (FDTD) method for simulating light scattering of spheres in a range of size parameters x up to 80 and refractive indices m up to 2. Using parallel implementations of both methods, we require them to reach a certain accuracy of scattering quantities. We show that relative performance sharply depends on m with boundary value of 1.4. DDA is faster for smaller m, while FDTD - for larger.
