Abstract
We report the experimental and theoretical study on the complementary planar metamaterial with asymmetrical air nanorods. Three high-quality samples are fabricated by the focused ion beam technique. Multi-band Fano-like resonances and selective electric field confinement in the visible-near infrared range are presented and well explained by the bonding/anti-boding and coupled mode theories of plasmonic resonators.
