Research

Hou-Tong’s research at CINT focuses on metamaterials and surface plasmonics, mainly in the terahertz frequency range. These involve the design, numerical simulation, fabrication, and characterization of passive, dynamical, and active metamaterial and surface plasmonic devices. His recent activities include dynamical and active hybrid metamaterials, metamaterial antireflection and perfect absorption, superconducting metamaterials, as well as metamaterials for flat optics. He is also interested in terahertz time domain spectroscopy, ultrafast laser spectroscopy, and scanning near-field microscopy for material and device characterizations.
