摘要：

We report an experimental and theoretical study of the optical properties of two-dimensional arrays of aluminum nanoparticle in-tandem pairs. Plasmon resonances and effective optical constants of these structures are investigated, and strong magnetic response as well as negative permeability is observed down to 400 nm wavelength. Theoretical calculations based on the finite-difference time-domain method are performed for various particle dimensions and lattice parameters, and are found to be in good agreement with the experimental findings. The results show that metamaterials operating across the whole visible wavelength range are feasible. (C) 2010 Optical Society of America
