Research projects in the Terahertz Electronics Laboratory, University of California Los Angeles, involve analytical and experimental studies on the use of new materials and device concepts to mitigate performance limitations of existing terahertz and millimeter-wave devices. Directed by Prof. Mona Jarrahi, our team works on the development of novel high-performance terahertz sources, detectors, spectrometers, reconfigurable meta-films, imaging and spectroscopy systems that leverage photonic, plasmonic, and MEMS concepts. We employ the developed terahertz device technologies for terahertz applications in material characterization, stand-off chemical detection, atmospheric studies, biological analysis and medical imaging.
