Light Scattering by Oriented and Randomly Dispersed Chiral Particles

摘要

The use of coupled dipoles in modelling light scattering by oriented and randomly dispersed chiral particles is examined in this paper. The chirality considered here is form chirality which results from macroscopic structural mirror asymmetry in the particle. For a chiral particle described by spherical dipoles, it is shown that large magnitude terms that contribute the chiral matrix elements of an oriented particle do not contribute at all in the orientation average. This result will be used in future work to obtain a more efficient method of evaluating light scattering by randomly dispersed chiral particles. (ERA citation 12:049040)
