The terahertz wave is a next-generation electromagnetic wave (0.1-10 THz) that is receiving much attention in recent years as 6G communication is highly feasible in the near future. The terahertz wave & electromagnetic wave application lab mainly focuses on 1) high-power compact terahertz wave generation techniques and 2) electromagnetic wave application research.
Our lab is trying to implement high-power terahertz waves using the concept of a traveling wave amplifier using vacuum electronics microfabrication. We are pursuing next-generation communication/security/medical application research through freely implementing electromagnetic wave manipulation through focusing of electromagnetic wave beams, generation of multiple rotation modes, and interaction with materials.
