  • Current Research Interests

    We are interested in topics related to the waves and beams. From the fundamental questions to the ultimate applications regarding electrodynamics, we are investigating how electromagnetic waves interact with charged particle beams. Here are some lists of current research interests:

    • Air plasma and gas discharge via microwaves
    • Remote detection of radioactive material
    • Micro-vacuum electron devices
    • High power millimeter/THz wave sources
    • THz based material characterization
