Paper Abstract

We report on the fabrication and characterization of a micro periodic structure realized in soft-composite materials containing metallic nanoparticles. The particles are used to infiltrate a passive polymer template realized by combining a holographic curing setup and a microfluidic etching process. In other experiments, small amounts of nanoparticles are dissolved in the original mixture utilized for the realization of polymer-liquid-crystal-polymer-slices gratings (POLICRYPS); this enables to fabricate POLICRYPS-like structures showing novel electromagnetic properties. Obtained structures are characterized in term of impinging probe polarization in the UV/visible range. Correlation between the optical response and external perturbations (electric field, temperature) is also reported. These first attempts are oriented to the fabrication of devices with tunable metamaterial properties.
