Liu Ruopeng arrived at Duke University in the early 2000s to begin doctoral studies under Professor David Smith. In 2010, Dr. Ruopeng cofounded Kuang-Chi Institute of Advanced Technology in Shenzhen, often called “China’s Silicon Valley.” In 2012, Xi Jinping visited Kuang-Chi on his first state industrial visit as president and received a personal briefing by Ruopeng on the current and potential applications of metamaterials.1 In 2018, when trade relations deteriorated between the United States and China, NBC highlighted the controversial and unauthorized transfer of Duke University’s metamaterial research by Ruopeng to China. He claimed that he transferred only basic research; Professor Smith disagrees, pointing to an exact replica of Duke’s microwave cloaking model built at Zhejiang University.2 In the end, China made boundless advances in the field of metamaterials without consequence.
