Excitation, Interaction, and Scattering of Localized and Propagating Surface Polaritons
… and confinement of the local electric field at optical frequencies. The local electric field can be further increased by tailoring the shape of the particle or by using near-field-interacting dimers or trimers of gold nanospheres. The hot spots found under such conditions increase the …

Time Domain Integral Equation-Based Methods for Analyzing Electromagnetic Scattering From Objects Residing in Lossy Media
… space and is able to speed up the evaluation of fields radiated by band-limited and time-limited sources far enough away. When these two techniques are hybridized in the MOT scheme, i.e., the recursive convolution scheme evaluates the near-field interaction, and the multilevel PWTD algorithm …

Metamaterial enhanced coupling
… to coupling with dielectric materials, the near field response of a metamaterial can also couple with another metamaterial. Subsequently, this thesis investigates the coupling between a pair of identical split ring resonators, and develops a general framework for evaluating the mode …

Fundamental Limits on Antenna Size for Frequency and Time Domain Applications
… radiation, it is shown that the entire antenna fields contribute to both radiation and energy storage with varying total energy velocity during the radiation process. These observations were obtained through investigating impedance, power, the Poynting vector, and energy velocity of a radiating …

A Theoretical Study on the Effect of Curvature on Near-field Radiative Transfer
… focuses on the theoretical analysis of near-field electromagnetic wave effects in thermal radiative transfer i.e. wave effects like interference, diffraction, and tunneling effects, that become important when analyzing energy transfer via electromagnetic waves over sub-wavelength …

Unified conformal/nonconformal domain decomposition methods for solving large-scale multi-region electromagnetic problems
… and polarizations. Fifth, waveguide modal fields are employed to expand the dual unknown of the nonconformal FETI method for scattering analysis of deep cavities. The dimension of the resultant global interface system matrix is reduced significantly and a direct solver based on block …
