The formation of medium with artificial optical activity

Physical optics

For the purpose of the formation of local chiral surrounding of a given medium point the orbit method of symmetry group is proposed. Gyration tensor is calculated by Discrete Dipole Approximation (DDA) method. The dependence of gyration tensor on cross dipole-toroidal polarizability tensor is established. Examples of computation of the rotation polarization angle which is considered as a function of local environment structure parameters are given.
