Numerical modeling tools are widely used in the design and
optimization of devices based upon liquid-crystal materials.  These
include display devices as well as other applications (such as
beam-steering devices).  The modeling typically requires two stages:
first, the computation of the equilibrium molecular orientational
properties in the liquid-crystal layer (which determine the spatially
varying optic axes of the uniaxial-crystal-like material), and second,
the calculation of the transmission and reflection of light
propagating through this inhomogeneous, anisotropic medium.  We report
on work in progress to adapt techniques from computational
electromagnetics to the numerical solution of the latter problem.
