Electromagnetic spectra of VSRR dimers.

(a) Simulation and (b) experimental transmittance spectra for VSRR dimerswith various gaps. The colored shade highlights the position for eachresonance mode. (c) Surface current density (in arbitrary unit andlogarithmic scale) of the VSRR dimer with G = 50 nm undernormal illumination at respective resonance wavelengthωa+b andωa−b as indicated in (a).Arrows present the direction of induced surface current. Right: directionsof induced electric and magnetic dipoles.
