Electromagnetic phenomena in photonic nanostructures

Out interests are to study various electromagnetic phenomena supported by isolated nano-scale metallic/plasmonic or dielectric elements as well as arrayed elements residing in free space or coupled with structured and layered metal-dielectric surfaces. The study is geared towards identifying novel applications of the investigated structures and phenomena including subwavelength lasers (supported by DARPA) as well as wave guiding and focusing structures for surface microscopy (supported by NSF).

Magnetization dynamics in magnetic nanostructures

Here, out interests are to study magnetization dynamics mechanisms in magnetic nanostructured materials. These mechanisms include dynamics of magnetization reversal in composite and patterned media for ultra-high density magnetic recording, composite media for microwave assisted magnetic recording, heat-assisted magnetic recording, as well as magnetic random access memory elements. This research is conducted in collaboration with the research groups in the Center for Magnetic Recording Research at UCSD as well as our industrial partners.

Analytic and computational methods in Electromagnetics, Optics, and Magnetics

The investigation of the photonic and magnetic nanostructures is based on the development of sophisticated analytical models and efficient numerical. We develop efficient analytical and numerical methods to compute electromagnetic/optical/magnetic fields in complex configurations. Many of these methods are based on integral formulation methodology.
