Abstract

The angular dependence of the reflectance from an isotropic medium with large, randomly oriented, ordered domains is investigated and compared with that of an isotropic medium in which the optical properties can be characterized by a scalar dielectric function. Employing average reflectance and transmittance theory, we demonstrate that an isotropic medium consisting of optically large ordered domains exhibits only a parallel-polarized reflectance minimum, not the formal zero expected at Brewster’s angle. We attribute this result to the existence of nonzero cross-polarization terms despite the random orientation and the application of an incoherent averaging scheme, which is used to mimic traditional light sources.

Note that this size effect is purely optical in nature, independent of material properties with the exception that the optical constants are anisotropic in the ordered or single-crystalline form and that the size effect clearly depends on the wavelength. (In the visible spectral range, e.g., ordered regions must be considered large if their diameter exceeds 30–70 nm.)

  17. Because of the excellent resemblance between the experimental and the theoretical curves, we have not considered scattering or coherence-related effects in our model for the large-domain case. The assumption of coherence-related effects, in particular, would lower the agreement between modeled and measured spectra.4
