    Abstract

    Metamaterial structures fabricated using nanoimprint lithography, allow large areas to be patterned quickly through multiple use of a nanoimprint stamp. The fabrication process produces fishnet structures of various dimensions on a polymer layer with metal-dielectric-metal compressed rectangular pillars. Simulations show negative refractive index and good figures of merit. However both of these figures could be increased by removal from the underlying polymer structure. We also report on the use of asymmetric spilt ring resonators used to detect small quantities of hormone estradiol by tuning the plasmonic resonances near the molecular resonance of the C-H stretch at nominally 3.31 microns.
