Abstract
A metamaterial‐based plasmonic sensor composed of thin metal and polymer layers deposited on top of a highly ordered porous alumina exhibits a sensitivity of more than 4800 nm per refractive index unit in the visible spectral range. The device is robust, cheap, has a large functional area of about 2 cm2, and the overall transmission is tunable by varying the film thickness.
