Changes in the spectrum produced by scattering from a synchronous rotation system of two anisotropic particles

The scattering of a polychromatic plane light wave incident upon a synchronous rotation system of two anisotropic particles is investigated. The analytical expression for the spectrum of the scattered field is obtained. Numerical examples are given to show the phenomena of spectral shift and spectral switch of the scattered field during the synchronous rotation of the two anisotropic scatterers. The influences of the off-center parameter and the direction of scattering on the spectral changes are discussed. (C) 2016 Elsevier GmbH. All rights reserved.
