    • Electrically Driven Terahertz Metamaterial Diffractive Modulator 

      Karl, Nicholas (2014-09-19)
      This thesis describes a method for terahertz (THz) modulation using active metamaterials. At optical and telecom frequencies, modulation of freely propagating and guided signals is an important concept that is fundamental ...
    • Graphene Photonic Devices for Terahertz and Mid-Infrared 

      Gao, Weilu (2013-11-08)
      Graphene and other strictly two-dimensional materials are the rising stars on the horizon of material science, condensed matter physics and engineering. The richness of optical and electronic properties of graphene attract ...
    • Imaging with Terahertz Pulses 

      Dorney, Timothy D.; Johnson, Jon L.; Mittleman, Daniel M.; Baraniuk, Richard G. (2000-07-01)
      Recently, a real-time imaging system based on terahertz (THz) time-domain spectroscopy has been developed. This technique offers a range of unique imaging modalities due to the broad bandwidth, sub-picosecond duration, and ...
    • Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials 

      Ren, Lei; Zhang, Qi; Nanot, Sébastien; Kawayama, Iwao; Tonouchi, Masayoshi; Kono, Junichiro (2012)
      Low-dimensional carbon nanostructures, such as single-wall carbon nanotubes (SWCNTs) and graphene, offer new opportunities for terahertz science and technology. Being zero-gap systems with a linear, photon-like energy ...
