(i) Metasurfaces and heat generation
Very recently, plasmonics has fostered another realm of applications in which dissipative effects are being advantageously utilized. Besides their widely used propensity to enhance and confine the near–field electromagnetic intensity, metal particles and nanostructures have revealed a great potential as local heat sources. This activity is developed both at the experimental level (including local temperature measurements through local spectroscopy) and a completely self—consistent scheme based on the Green Dyadic Functions (\sf GDF) formalism that compute the local field intensity and temperature distribution inside and around a particle array by including the coupling with the substrate. This scheme is applied to design and optimize new concepts of thermoplasmonic metasurfaces integrated in coplanar geometry [4,5].
