Surface and Magnetic Polaritons on Nanodisk-Aligned Multilayer Structure.
Master's Thesis, University of Pittsburgh.

Abstract
In this thesis, the nanodisk-aligned multilayer structure, in which square cross-sectional nanodisks are vertically aligned on the top of a two-dimensional, dielectric-layered metallic structure, is proposed to investigate the near-filed and far-field radiative property enhancement for metamaterials. Multiple kinds of plasmonic resonances which support the peculiar properties of metamaterials have been identified on this proposed structure. Every plasmonic mode is analyzed and studied respectively. The localized plasmonic modes (Localized Surface Plasmon and Magnetic Polariton) are shown to be independent of the incidence angle and polarization, while the propagating plasmonic mode (Surface Plasmon) is demonstrated to be shifted with the varying of the incidence angle, which provides the possibility to make the plasmonic modes interact or couple with each other. The coupled plasmonic modes which are named as hybridized plasmonic modes can also be excited and lead to even more spectacular radiative properties both in the near-field and far-field.The results obtained from this study suggest a novel model to explore the underlying mechanism of plasmonic resonances, especially for their hybridization. The study will advance our fundamental understanding of light-matter interaction at nanometer scale and will provide us more degrees of freedom to manipulate the radiative properties in both the near-field and far-field which might have great potentials in renewable energy applications that require specific radiative properties, such as thermophotovoltaic, photovoltaic cells and thermal emission sources.
