Faculty Host: Associate Professor Luca Dal Negro (ECE, MSE)

Refreshments will be served outside Room 339 at 3:45 p.m.

Abstract: Designer electromagnetic materials, known as metamaterials, have enabled novel realizations of negative index of refraction, invisibility cloaks, and perfect lenses. Metamaterials is now a decade old mature research field and focus has shifted toward demonstration of applications. Recently near unity absorption has been achieved with metamaterials and results show that the fundamental light interactions of surfaces may be dynamically controlled. We show metamaterial based spatial light modulators operating at terahertz and infrared frequencies which permit coded aperture single pixel imaging and compressive imaging.

About the Speaker: Willie Padilla received a Ph.D. in physics from the University of California, San Diego in 2004. From 2004 to 2006, he was a Directors Postdoctoral Fellow at Los Alamos National Laboratory. In 2006, he joined the Department of Physics at Boston College and is currently an Associate Professor. In 2007, he was awarded a Young Investigator Award from the Office of Naval Research and a Presidential Early Career Award for Scientists and Engineers in 2011. In 2012, Professor Padilla was elected a Fellow of the Optical Society of America. His scientific interests include artificially structured systems including electric and magnetic metamaterials, active/dynamic metamaterials, photonics, nano-structured materials, transformation optics and negative index materials.
