110 Cummington Mall, Room 245
The Department of Mechanical Engineering is happy to announce:

Willie Padilla:
Terahertz and Infrared Metamaterials for Imaging and Energy Harvesting Applications
Boston College

Metamaterials are designer electromagnetic materials that consist of subwavelength, periodic metallic inclusions. Experimental realizations of negative index of refraction, invisibility cloaks, and perfect lenses demonstrate the ability of metamaterials to achieve exotic electromagnetic responses. Metamaterials is now a mature research field and focus has shifted toward demonstration of viable 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 tailoring of emission, thus enabling energy harvesting applications.

About the speaker:
Willie Padilla received a physics PhD from the University of California San Diego in 2004 and was a Directors Postdoctoral Fellow at Los Alamos National Laboratory - 2004 to 2006. In 2006 Professor Padilla joined the Department of Physics at Boston College and is currently an Associate Professor. In 2007 Prof. Padilla was awarded a Young Investigator Award from the Office of Naval Research and Presidential Early Career Award for Scientists and Engineers in 2011. In 2012 Professor Padilla was elected a Fellow of the Optical Society of America. Scientific interests include electromagnetic metamaterials.

Refreshments will be served at 10:45 am.
