Mapping gigahertz vibrations in a plasmonic--phononic crystal

Video abstract for the article 'Mapping gigahertz vibrations in a plasmonic--phononic crystal' by Timothy A Kelf et al 2013 New J. Phys. 15 023013. ntroduction and background. Metals exhibit plasmonic properties, involving the coupling of electromagnetic fields to electrons, that promise applications in photonic nano-circuits and sensing. The phononic properties of metal structures are also very important in making filters in telecommunications. Here we map for the first time the interaction...
