The combination of singular optics and partially coherent fields has become increasingly important in the applications of optical communication and optical imaging. Withi[...]

Singularities defining the topology for the polarization state of nonuniformly polarizedelectromagnetic beams have been a topic of both theoretical and practical interest[...]

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 usin[...]

Surface plasmon effects in nano-optical systems are investigated through rigorous numerical simulations and analytical modeling. Several strategies to achieve superresolu[...]

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 opti[...]

Superoscillation is a physical phenomenon, in which the local oscillations of a bandlimited signal fluctuate faster than the fastest Fourier component of the signal. In r[...]

In 1980s a processor had only one core, whose performance was improved by increasing the processor frequency. But this caused overheating and thus improvement in performa[...]

Substance abuse has devastating social, economic, and public health consequences. For pregnant, post-partum, and parenting women who abuse substances, fetal and child de[...]

The orbital angular momentum of light is a promising candidate as an information carrier in optical communication systems to enhance the capacity of data channels. Howeve[...]
