Terahertz and Infrared Compressive Imaging with Metamaterials
Metamaterials are artificial electromagnetic materials which have realized exotic electromagnetic responses including negative index of refraction and invisibility cloaking. As the underlying physics of these fascinating materials continues to be uncovered, effort is now shifting toward demonstration of devices. I will present the design, fabrication, and demonstration of active metamaterial absorbers that function as a real-time tunable, spectrally sensitive spatial masks for use in THz imaging with only a single pixel detector. I will also overview the physics underlying operation of the metamaterial absorber and contrast them with alternative approaches.
Willie Padilla received a PhD from the UC San Diego and was a Director’s Postdoctoral Fellowship at Los Alamos National Laboratory. In 2006 he joined the Department of Physics at Boston College and is a Full Professor. In 2007 he 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 he was elected a Fellow of the Optical Society of America and a Kavli Frontiers of Science Fellow in 2013.
