In 2005 Alu and Engheta proposed using gold loops to construct a sort of invisibility cloak based on these. The polariton type of these are attractive candidate carriers for proposed photonic circuits. The typical energy scale for these is tens of electronvolts as can be found by measuring the energy lost by electrons fired through thin films. Their characteristic frequencies define the transmission bandwidth of metals. A variety of these localized to surfaces was predicted in 1957 by Rufus Ritchie; the sensitivity of that type to variations in the dielectric constant is the basis of surface-enhanced Raman spectroscopy. For 10 points, name these quasiparticles, quanta of collective vibrations of the electron gas in metals.
