The effective optical properties have been investigated in granular insulator/liquid host composite media- In the weak nonlinearity limit, we calculate numerically the effective linear dielectric function (ε0e) and optical nonlinearity (χe) as functions of the volume fraction of insulator inclusions (f)-The results show that χe can be achieved at a resonant frequency ω≈32- In the general nonlinear case, we study how the intensity of incident light affects the effective dielectric function- Furthermore, the total effective refectances of s-and p-polarized light are investigated-
