Extract

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.
