Abstract
We present a surface plasmonic resonance sensor composed of Ag strip pairs array embedded in the background material. The calculated results demonstrate that one of the transmission dips of the structure is very sensitive to the background materials. Meanwhile, the structure could achieve the sensitivity (nm/RIU) about 700 nm/RIU, when the slits width of Ag strip pairs is 10 nm.
