Dr. Jason Valentine, assistant professor of both mechanical and electrical engineering at Vanderbilt University, got his start in cloaking research as a graduate student at the University of California, Berkeley.

“We made the first cloak that worked at optical frequencies,” says Valentine. “It wasn’t quite visible light, but it was sort of a proof of concept that we could make these structures at high frequencies.”

While previous cloaking research focused on the use of microwave frequencies, such as the research completed by Duke University scientists in 2006, Valentine did his research under Dr. Xiang Zhang, professor of mechanical engineering and director of the LBNL Materials Science Division at Berkeley. The team focused on the use of metamaterials in order to create a cloaking device.
