Abstract: Located at the interface between classical electronics and quantum photonics, terahertz technology has been challenging due to the deficiency of materials with useful response for the construction of terahertz devices and components. The emergent electromagnetic metamaterials provide new opportunities in solving this terahertz gap due to the resonant enhanced interaction between terahertz waves and materials. In this talk I will introduce the novel functionalities achieved using terahertz metamaterials and devices. These include dynamical and/or active switching and modulation of terahertz waves, frequency tunability, antireflection and perfect absorber, and superconducting metamaterials. The underlying mechanisms will also be discussed.

Biography: Hou-Tong Chen received his B.S. and M.S. degrees from University of Science and Technology of China in 1997 and 2000, respectively, and a Ph.D. degree from Rensselaer Polytechnic Institute in 2004, all in Physics. He joined LANL as a Postdoctoral Research Associate in May 2005, and then was converted to a Technical Staff Member in June 2008. Currently he is a Staff Scientist in the Center for Integrated Nanotechnologies, Materials Physics and Applications Division, at LANL. Dr. Chen's research interests include ultrafast optics and terahertz time-domain spectroscopy, and electromagnetic metamaterials and devices for terahertz applications. He was a recipient of the LANL Postdoc Publication Prize Honorable Mention and the LAAP Achievement Award, both in 2007.
