Optical Anisotropy of Nanotube Suspensions



Erik K. Hobbie


A semi-macroscopic model of an optically anisotropic absorbing nanotube suspension is derived perturbatively from Maxwell s equations in a dielectric medium. We calculate leading-order expressions for the intrinsic and form contributions to the complex dielectric tensor, valid in the dilute and semi-dilute limits, in terms of the nanotube volume fraction, the optical anisotropy of the individual tubes, and the optical contrast with the solvent. The birefringence and dichroism are derived in some limiting scenarios of practical interest, and the connection to depolarized light scattering is established.
