The variation of the refractive index of the fiber material with the wavelength for light polarizing parallel to the fiber axis can be given from the Cauchy's dispersion formula given from Ref.
The VAWI technique verifies the Cauchy's dispersion formula and its constants, which related to the molecular arrangement of annealed iPP fiber with the wavelength of the incident light beam.
Without going into too much detail, in the remaining section we will follow the logic of deriving [[epsilon].sub.LFE-9], the first-order analytic dispersion formula
[12, Equation (43)] for the 2D LFE-9 stencil.
The use of a horizontal media mill is of common practice when evaluating a dispersion formula
, so an understanding of the effect of grind time on particle size of this system was desired.

On the basis of effective constant [[epsilon].sub.i,e] (0) computed above, a dispersion formula for effective constant [[epsilon].sub.i,e](f) was proposed in , where f is the operating frequency.
