The goal of this dissertation is to extend the understanding of invisible objects, in particular nonradiating sources and directional nonscattering scatterers. First, variations of null-field nonradiating sources are derived from Maxwell's equatio...

Nonpropagating excitations have been studied in 1-D and in 3-D, but not so much in 2-D. So, this thesis concerns 2-D nonpropagating excitations. In particular, we construct nonpropagating excitations confined to an annulus under a time-independent...

In this dissertation, we use theory and computation to conduct three projects in the area of nano-optics. In the first project, we study optical coherence conversion using a plasmonic hole array. This work led to the discovery of the optical coher...

The use of nonconventional beam classes in turbulence applications is investigated. Through the study on pseudo-Bessel correlated beam propagation in the atmosphere, it is shown that scintillation reduction by a partially coherent beam can be obta...

Vortices in optical beams have been the subject of extensive study since their status as a generic feature of light was established. They have found extensive use in optical trapping systems, astronomy, microscopy and are being investigated for fr...
