| Abstract: | The energy band structure of nonlinear superlattice is analyzed and the transmission multistability is shown.The nonlinear Schrodinger equation of the nonlinear Kronig-Penney superlattice is transformed to a set of two-dimensional real map.Numerical solutions give the energy band structures which depend on the nonlinear coefficient and wave intensity.And the multistability of transmission with a certain incident wave is presented. |

| Keywords: | nonlinear Kronig-Penney superlattiee two-dimensional real map the power of incidence transmissive coefficient multistability |
