The measurement of a photonic signal via plasmon-plasmon coupling in curved thin metal films is presented. In domains of subwavelength dimension, we calculate the resonant dispersion relations by modeling the curved thin film as a single sheeted hyperboloid of revolution. We show that several such surface modes are accessible optically at frequencies below the plasma frequency of the metal.

    The physical origin of quantum-size effects (QSEs) and its impact on the decay length of electrons in Pb thin films are studied by first-principles calculations. We show that QSE is not only size but also wavevector dependent: being maximum at [formula] due to strong interlayer coupling between...
