Dielectric function of nonlinear metal composite with double-layer ellipsoidal inclusions

Abstract

The nonlinear dielectric properties of heterogeneous material are intensively studied during last time. It was discovered the effect of enormous enhancement for non-linear optical responses in composite material containing metal particles as inclusions. These metal particles are much smaller than a wavelength of the electromagnetic radiation but large enough to be considered a bulk material. Their typical size is several nonometers.
