Abstract

We study nonlinear dielectrics obeying D = ε{lunate}(E2)β/2E. The solution to the eletrostatic equations is found to be unique for ∞ α = 1/(β + 1) 1/(d - 1). We find the electrostatic fields produced by a point charge and by an infinite charged slab in such a medium. Two definitions of the effective dielectric constant, ε{lunate}eff, are shown to coincide. For the case where ε{lunate} varies in space we show that the differential equation for the first correction to the potential field is dipolar in scaled coordinates. We use the first correction to bound ε{lunate}eff. Finally we formulate the explicit time dependent equations that describe the dynamic behavior of the magnetic and electric fields in such materials.
