Electromagnetic response of isolated VSRR.

Experimental transmittance spectra for isolated VSRR with 500 nmperiod in x and y directions on a glass (BK7) substrate. The purple andorange spectral lines correspond to the isolated VSRR with L =170 nm and 220 nm, respectively. The resonancedifference is about 20 THz in frequency indicated by the magentadashed lines. The images on right represent the top view SEM pictures of thecorresponding structures. Scale bars: 250 nm.
