Plasmonic metamaterials are engineered materials that manipulate electromagnetic waves at scales smaller than the wavelength of light, leveraging the principle of surface plasmon resonance. They typically consist of metallic nanostructures, which can support surface plasmons—coherent oscillations of free electrons at the interface between a metal and a dielectric (non-metal) material.
