We proposed a refractive index sensor based on double-side metal-coated dielectric nanoslit array. The structure shows extremely sharp resonance peak adjacent to anti-resonance peak and the FOM is 156. Also, we can obtain ultra-high sensitivity of 889 nm/RIU over wavelength ranging from 1182 nm to 1262 nm
