Light(electromagnetic waves)plays an indispensable role in modern society, utilized in communication, measurement, and more. In this laboratory, we are developing technologies to control light with unprecedented precision using metamaterials, which are artificially engineered materials. Before the advent of metamaterials, control of light was achieved using natural substances(for example, glass lenses). However, the emergence of metamaterials, substances whose properties can be artificially designed, has opened up seemingly infinite possibilities for controlling light. Our laboratory designs metamaterials using electromagnetic field simulators, their fabrication and experimental testing.
