Calculated Reflection Coefficients of a Single Planar Interface with an Optically Biaxial Cu(en)(H2O)(2)SO4 Material Compared to Experiment

摘要

In our previous work we presented ellipsometric measurement of (ratios of) reflection coefficients of a planar interface between air and a facet of a single-crystal monoclinic (i.e., anisotropic) material Cu(en)(H2O)(2)SO4, en = C2H8N2. The reported dependence of the coefficients on azimuthal orientation of the crystal, Figure 1 below, showed features which were ascribed to misalignment from the then-assumed ideal orientation. Here, using Berreman's formalism, we show on theoretical grounds that misalignment may truly result in the observed findings.
