%X Based on FDTD method,a two dimensional model for metamaterial volume with regular triangle,quadrangle and hexagon structure under light irradiation was presented.The focus characters of the model were analyzed and its validity was tested.The simulation results show that when light wave propagates along the angular bisector of corner angle in metamaterial volume,the electromagnetic focus effect will not exist in the metamaterial volume,although the permittivity and permeability of metamaterial are very small.
