Nanoporous Plasmonic Metamaterials

Abstract

Abstract We review different routes for the generation of nanoporous metallic foams and films exhibiting well‐defined pore size and short‐range order. Dealloying and templating allows the generation of both 2D and 3D structures that promise a plasmonic response determined by material constituents and porosity. Viewed in the context of metamaterials, the ease of fabrication of samples covering macroscopic dimensions is highly promising, and suggests more in‐depth investigations of the plasmonic and photonic properties of this material system for photonic applications.
