During the past decade electromagnetic metamaterials have realized many exotic phenomena that are difficult or impossible to occur in nature. Novel functionality in metamaterials usually originates from their resonant interaction with electromagnetic waves. It becomes increasingly important in the terahertz frequency range, where the so-called terahertz gap is a technology vacuum associated with the deficiency of terahertz materials. In this talk, I will demonstrate how passive and active terahertz metamaterials and devices have enabled novel functionality and unprecedented performance. These will mainly cover design of novel metamaterial structures, resonance tuning through integration of semiconductors and complex oxides, as well as thin metamaterial coatings for antireflection and perfect absorption.


Dr. Hou-Tong Chen (陈侯通) received his B.S. and M.S. from University of Science and Technology of China in 1997 and 2000, respectively, and a Ph.D. from Rensselaer Polytechnic Institute (RPI), USA, in 2004, all in Physics. After a short period of Postdoc Fellow at RPI, from 2005 to 2008 he was a Postdoctoral Research Associate at Los Alamos National Laboratory (LANL). He holds a Technical Staff Member position since 2008 in the Center for Integrated Nanotechnologies (CINT) at LANL, and is a CINT Scientist since 2010. His research areas include metamaterials and devices, nanophotonics and plasmonics, ultrafast optics and terahertz time domain spectroscopy, and terahertz scanning near-field microscopy.
