%X We present a numerical study of left-handed metamaterials (LHMs) composed of double cross pairs at visible frequency. The S-parameter retrieval method is adopted to confirm the negative refractive characteristic of this design. Compared with fishnet LHMs, the proposed cross LHMs have a much lower loss, which will greatly facilitate practical applications. It is also found that, with the same size of resonant cells, the cross LHMs have a higher frequency than fishnet LHMs, which is explained using a simple effective LC circuit model.
