**ABSTRACT:**A type of negative-index metamaterial composed of periodic arrays of SRRs is proposed and numerically investigated in the visible frequencies. Employing the high order magnetic resonance to induce negative permeability, negative refractive index is obtained between 395 THz and 430 THz with the maximum FOM=4.59. The effective permeability exhibits a rapid convergence with increasing number of metamaterial layers. Different responses from the electric and magnetic resonances to the changing geometric parameters are compared and analyzed in terms of the field distribution. Simulation results show that the high order magnetic resonance can be greatly enhanced at visible frequencies as well as effectively tuned over a wide spectral range without notably altering the coupling between unit cells.Applied Optics 05/2012; 51(13):2469-76. · 1.69 Impact Factor - [Show abstract] [Hide abstract]

**ABSTRACT:**We analyze the resonant electromagnetic response of sub-wavelength plasmonic dimers formed by two silver strips separated by a thin dielectric spacer and embedded in a uniform dielectric media. We demonstrate that the off-resonant electric and resonant, geometric shape-leveraged, magnetic polarizabilities of the dimer element can be designed to have close absolute values in a certain spectral range, resulting in a predominantly unidirectional scattering of the incident field due to pronounced magneto-electric interference. Switching between forward and backward directionality can be achieved with a single element by changing the excitation wavelength, with the scattering direction defined by the relative phases of the polarizabilities. We extend the analysis to some periodic configurations, including the specific case of a perforated metal film, and discuss the differences between the observed unidirectional scattering and the extraordinary transmission effect. The unidirectional response can be preserved and enhanced with periodic arrays of dimers and can find applications in nanoantenna devices, integrated optic circuits, sensors with nanoparticles, photovoltaic systems, or perfect absorbers; while the option of switching between forward and backward unidirectional scattering may create interesting possibilities for manipulating optical pressure forces.Optics Express 12/2013; 21(25):31138-54. · 3.55 Impact Factor - [Show abstract] [Hide abstract]

**ABSTRACT:**We introduce a simple but general mechanism to realize the dual magnetic resonance exhibiting a broadband negative permeability. A satisfactory explanation, based on the second-order hybridization of symmetric metamaterials, for resonant splitting is given. It is manifested that the geometric correlation plays a vital role in controlling the hybridization strength. Transfer matrix simulations and equivalent circuit model analysis are performed to corroborate our idea.Applied Physics Express 11/2012; 5(11):2001-. · 2.73 Impact Factor
