Epsilon-near-zero materials: Optical properties and applications

Guest Speaker:

Salvatore Campione of Sandia National Laboratories, P.O. Box 5800, Albuquerque, NM, 87185, USA


Epsilon-near-zero (ENZ) materials have attracted attention in recent years as a new path for tailoring light-matter interactions at the nanoscale. In this talk, I will review some of the basic optical properties of ENZ materials and provide an overview on how these materials were exploited in several applications, including perfect absorption, ultrafast polarization switching, tunable metasurfaces, and high-speed optical modulators.

 Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-NA000352.


Salvatore Campione received a Laurea triennale and a Laurea Magistrale degrees (both cum laude) in electronic engineering from the Polytechnic of Turin, Torino, Italy, in 2007 and 2009, respectively, a Master of Science degree in electrical and computer engineering from the University of Illinois at Chicago, Chicago, IL, USA, in 2009, and a Doctor of Philosophy degree in electrical and computer engineering from the University of California Irvine, CA, USA, in 2013. In 2014, he joined Sandia National Laboratories, Albuquerque, NM, USA, as a Postdoctoral Fellow, and became a Senior Member of the Technical Staff in 2016. He has published more than 75 peer-reviewed journal articles, more than 110 conference papers, three issued patents, and two book chapters. His research interests include electromagnetic theory, antennas, metamaterials and their applications, plasmonics in nanostructures, and optical devices for energy and optoelectronic applications. Dr. Campione is a Senior Member of IEEE, an Individual Member of the International Union of Radio Science (URSI), and a member of the IEEE Eta Kappa Nu, the IEEE Photonics Society, the IEEE Antennas and Propagation Society, and the IEEE Microwave Theory and Techniques Society. Among other awards, he received a 2013 Marconi Society Paul Baran Young Scholar Award, a 2013 IEEE Photonics Society Graduate Student Fellowship, the 2016 IEEE Eta Kappa Nu Outstanding Young Professional Award, and the 2017 Applied Computational Electromagnetics Society Early Career Award.
