Abstract
The coupled-dipole method is widely used to calculate the light-scattering matrix S from arbitrary particles. An important parameter in the model is the size of the dipolar subunits. Usually a size of ~1/10 to ~1/20 of the wavelength of the incident light is sufficient for accurate calculations. However, it was noted that accurate S(34) calculations require much smaller dipolar subunits. We show that this conclusion is too pessimistic, by examining the sensitivity of the S(34) elements on surface roughness of spherical particles. Furthermore we give an example of an accurate S(34) calculation with dipolar subunits as large as 1/10 of the wavelength.
