Accurate light scattering for non spherical particles from Mie-type theory

Abstract

We report a new approach for accurate calculation of optical cross sections and internal and scattered fields at any point in space for micro- and nanoparticles. Our approach is based on constructing the intrinsic optical modes of general smooth particles and hence optimised surface Green functions that, for any incident field, provide an a priori upper bound on the error and identify the class of incident fields with largest error.
