title: Computation of the internal field of a large spherical particle by use of the geometrical-optics approximation.
abstract: We obtain the internal electric field of an illuminated liquid droplet using geometrical optics. The approximation includes the phase effects of various components. We compare the geometrical-optics solution with the Mie theory solution for a nonabsorbing particle with a size parameter of alpha = 500 and an index of refraction of n = 1.332.
