A T-matrix approach for particles with small-scale surface roughness

We combine group theory with a perturbation approach Table Place Name to perform T-matrix computations for particles with small-scale surface roughness up to size parameters of 70.The optical properties of high-order 3D-Chebyshev particles differ substantially from those of spheres.CPU times are reduced by more than 4-5 orders of magnitude by the use of group theory, while the perturbation approach circumvents the notorious ill-conditioning problems Air Purifiers of the null-field method, thus allowing the treatment of large size parameters.
