Configurational average reflected field

Thus, the procedure is to first find the singular solution of the Lorentz-Lorenz law together with the dispersion relation for the effective wave number Kg, and then to determine the arbitrary constant from the scalar equations (2.190) or (2.191). After the conditional average of the scattered field coefficients has been evaluated, the coherent reflected field can be computed by taking the configurational average of (2.171), i.e.,... 

This theory has two notable features. The nonlocality of molecular interaction is reflected by the ellipticity of Eq. (19) [cf Eq. (15)]. Thus, the LCP configuration is globally coupled by distortional elasticity. In addition, the elastic stress tensor is asymmetric. The mean-field torque on LCP molecules amounts to a volume torque on the material, which modifies the usual conservation of angular momentum. The antisymmetric part of the stress tensor precisely balances the volume torque computed by averaging the molecular torque. ...
