Radiative interactions: I. Light scattering and emission from irregular particles. II. Time dependent radiative coupling of an atmosphere-ocean system
In the first part of this dissertation, radiative interactions with single irregular particles are simulated. We first introduce the basic method and techniques of Finite- Difference Time-Domain method(FDTD), which is a powerful method to numerically solve Maxwell's equations with high accuracy. To …

Wireless transfer of electric power
… is accomplished using inductive, near-field, non-radiative coupling between self-resonant copper helices. In our first experiment, we transfered 60W of power over a distance of 2m with 45% efficiency. In our second experiment, we designed a system which can transfer power from a single source to …

Nonlinear optical emission and near-field enhancement effects in arrays of gold bowtie nano-antennas
… A detrimental side-effect of the efficient radiative coupling to the incident light and high near-field intensities is laser-induced damage, which may alter the morphology of the BNA structures at sufficiently high laser fluences. A damage threshold is systematically determined in terms of …

Materials, photophysics and device designs for high efficiency photovoltaics
… Using a detailed balance model we show that the radiative coupling between the two sub-cells can result in an absolute gain of ~ 11% in the tandem cell’s efficiency. Next, we study a novel solution-processed pentacene precursor for applications in singlet fission sensitized photovoltaics and …

Triplet Exciton Management in Organic Electronic Devices
… excitons can be a source of loss due to poor radiative coupling to the ground state and energy loss on formation from the singlet state. In this thesis, methods of avoiding loss pathways through triplet states are investigated in both organic light-emitting diodes and organic photovoltaics. …

Nanoplasmonics and silicon nanophotonics devices for sensing applications
… field and the enhancement of EOT (due to radiative coupling of surface plasmons). The design principle of such devices for surface enhanced Raman spectroscopy (SERS) applications based on the classical electromagnetic simulations (Finite Difference Time Domain, FDTD) and the quantum …

Interactions of Organic Fluorophores with Plasmonic Surface Lattice Resonances
… This new plasmonic mode, formed by the mutual radiative coupling of the dipolar LSPRs of the individual plasmonic nanoparticles constituting the lattice, is known as a surface lattice resonance (SLR), sometimes described as a plasmonic SLR to distinguish it from lattice resonances supported by …
