Overview
Our laboratory is engaged in research on advanced devices for controlling the propagation of electromagnetic waves from the visible to the terahertz region, together with the functional materials employed in these devices. In particular, our recent research has focused on the development of metamaterial-based dynamic terahertz devices.
