Plasmon resonances in multilayer Fanoshells
Luke C. Ugwuoke, Tjaart P. J. Krüger
We develop a theoretical framework, based on a multipole, quasi-static approach, for the prediction of the localized surface plasmon resonances in Fanoshells formed via geometrical…

Plasmonic Quantum Yield Enhancement of a Single Molecule Near a Nanoegg
Luke C. Ugwuoke, Tomáš Mančal, Tjaart P. J. Krüger
We investigate the impact of the dipole-active modes formed via the mode-mixing of the dipole mode with higher-order surface plasmon modes of a nanoegg on the radiative decay rate…

Localized Surface Plasmon Resonances of Simple Tunable Plasmonic Nanostructures
Luke C. Ugwuoke, Tomáš Mančal, Tjaart P. J. Krüger
We derive and present systematic relationships between the analytical formulas for calculation of the localized surface plasmon resonances (LSPR) of some plasmonic nano-structures…
