Nader EnghetaAbstract

Recent development in nanotechnology, nanoscience and materials science and engineering has provided opportunities to engineer structures with unprecedented attributes and characteristics in manipulating waves and fields.  We are exploring light-matter interaction in platforms with extreme scenarios, such as near-zero permittivity and near-zero permeability, and with extreme features such as very high phase velocity, very low energy velocity, nonreciprocal vortices at the nanoscale, giant anisotropy and nonlinearity, “near-zero” photonics, nanoscale computation with optical nanocircuits, and more.  Such “sculpting waves at the extreme” will provide us with exciting features and functionalities for wave-based paradigms such as optics, acoustics, and thermodynamics.  I will discuss some of our ongoing work in these areas, will present some of the opportunities and challenges, and will forecast some future directions and possibilities.


Nader Engheta is the H. Nedwill Ramsey Professor at the University of Pennsylvania in Philadelphia, with affiliations in the Departments of Electrical and Systems Engineering, Materials Science and Engineering, Physics and Astronomy, and Bioengineering.  He received his B.S. degree from the University of Tehran, and his M.S and Ph.D. degrees from Caltech.

His current research activities span a broad range of areas including nanophotonics, metamaterials, nano-scale optics, graphene optics, imaging and sensing inspired by eyes of animal species, optical nanoengineering, microwave and optical antennas, and physics and engineering of fields and waves.  He has co-edited (with R. W. Ziolkowski) the book entitled “Metamaterials:  Physics and Engineering Explorations” by Wiley-IEEE Press, 2006.  He was the Chair of the Gordon Research Conference on Plasmonics in June 2012.
