Abstract
Arden L. Bement Jr. Distinguished Lecture
Hyperbolic metamaterials are strongly anisotropic composite media that behave as either metals or dielectrics in different directions. They can be fabricated n many different ways, such as metallic layers that are separated from each other by thin dielectric spacers, or using arrays of parallel metallic nanowires in a dielectric material.
Unique optical properties of hyperbolic metamaterials – from negative refraction to diffraction-less propagation and subwavelength focusing to accelerated light emission to enhanced radiative heat transfer – are transforming the ways we think about optical imaging, light-wave communications, and electromagnetic energy harvesting.
Bio
Evegenii Narimanov is a professor of Electrical and Computer Engineering in the College of Engineering. He received his master's degree n applied mathematics and physics and PhD in semiconductor physics from the Moscow Institute of Physics and Technology
After working at Yale University, Bell Labs/Lucent Technologies, and Princeton University, Narimanov joined Purdue University in 2007 as an associate professor. He became full professor in 2013.
His current research includes nanophotonics, physics of metamaterials, and information theory for optical imaging. Narimanov's work in optics and optoelectronics is recognized nationally and internationally. He has been credited with a series of research breakthroughs – from the development of the high-power microlasers with wave-chaotic dynamics, to the derivation of the fundamental information-theoretical limit on the communication rates in nonlinear fiber-optical networks. He pioneering work in hyperbolic metamaterials and discovery of the hyperlens has led to an optical device capable of resolution beyond the diffraction limit.
Narimanov has authored and co-authored four book chapters, more than 100 peer-reviewed articles, and has more than 100 conference presentations, including many invited and keynote talks. He has been awarded six U.S. patents.
He has been named Purdue University Faculty Scholar and is the recipient of the National Science Foundation Career Award. He is a fellow of the Institute of Electrical and Electronics Engineers and the Optical Society of America.
