Effective Dielectric Permittivity

AbstractWe study theoretically a nonlinear response of the planar metal/dielectric nanostructures constituted from periodical array of ultra thin silver layers and the layers of Kerr-like nonlinear dielectric. We predict hysteresis-type dependences of the components of the tensor of effective dielectric permittivity on the field intensity allowing the change in material transmission properties from transparent to opaque and back at extremely low intensities of the light. It makes possible to control the light by light in all-optical nanoscale devices and circuits.

ABSRTACT:An effective nonlinear dielectric permittivity of a heterogeneous composite structure consisting of coated ellipsoidal nonlinear nanoparticles embedded in a linear host medium has been theoretically studied. An expression for the effective dielectric permittivity tensor of such a system has been derived following the Clausius-Mossotti approximation. The conditions for the existence of electromagnetic bistability phenomenon in a single coated ellipsoidal particle with a nonlinear core and a metallic shell have been obtained. The numerical results show more prominent bistability phenomenon in more dense suspensions of nonlinear heterogeneous ellipsoids.
