Abstract


A method to retrieve both effective electric and magnetic nonlinear susceptibilities of metamaterials is presented. This method is applied to simplified unit cells with only electric nonlinearity to isolate the effect of spatial dispersion, which shows as a magnetic nonlinearity. A criteria for homogenization of nonlinear metamaterials is proposed.
