Conductivity of Metal Nanowires Studied by Infrared Plasmon-Polariton Spectroscopy
Metal nanorods of a few micron length and a much smaller diameter feature strong plasmonic resonances in the infrared region and therefore act rather similar to radio antennas, but the spectral shape of such resonances is related to the conductivity of the nanoantenna material. In the scientific literature, analytic approaches exist which explain the relationship between the electronic conductivity and the resonance spectrum that is due to plasmon polaritons as mixed excitations from free electrons and photons.
