Ultra-wide sensing range plasmonic refractive index sensor based on a two-dimensional circular-hole grating engraved on a gold film

We propose a simple structure with a two-dimensional (2D) circular-hole grating engraved on a gold film for ultra-wide range plasmonic refractive index (RI) sensing. The electromagnetic field distributions and reflection spectra of the structure are obtained using the finite-difference time-domain a...
