A direct method of measuring the nonlinear ER effects is to examine the frequency dependence of the same effects. For a sinusoidal applied field, we calculate the ac response which generally includes higher harmonics. In is work, we develop a multiple image formula, and calculate the total dipole moments of a pair of dielectric spheres, embedded in a nonlinear host. The higher harmonics due to the nonlinearity are calculated systematically.Presented at Conference on Computational Physics (CCP2000), held at Gold Coast, Australia from 3-8, December 2000Soft Condensed MatterMaterials Sciencetext
