N2 - Optical properties of the metallic nanoparticles are most often described in terms of plasmons, that is, coupled states of light and electrons. Here we show that many discrete resonances, resulting from the quantum confinement of electronic wavefunctions inside the metallic nanostructure, may lead to a single strong composite resonance, located typically in the low-frequency (mid-infrared and terahertz) range. They give rise to strong nonlinearities allowing efficient generation of terahertz and mid-infrared frequencies on the distances of just hundred nanometers. Especially effective are the processes which couple the quantum-confinement-induced resonances with Mie-type ones.
