Hongsheng Chen is a Chang Jiang Scholar distinguished professor at Zhejiang University and Vice-Dean of the College of Information Science and Electronic Engineering. He received the B.S. and Ph.D. degree in electronic engineering from Zhejiang University, Hangzhou, China, in 2000 and 2005, respectively. Since 2005, he has been with Zhejiang University, where he is currently a full professor. He was a Visiting Scientist (2006-2008) and a Visiting Professor (2013-2014) with the Research Laboratory of Electronics at Massachusetts Institute of Technology, USA.
His current research interests are in the areas of metamaterials, invisibility cloaking, transformation optics, and topological electromagnetics. He is the coauthor of more than 250 international refereed journal papers. His works have been highlighted by many scientific magazines and public media, including Nature, Scientific American, MIT Technology Review, The Guardian, Physorg, and so on. He is an author of the book Metamaterials and Negative Refraction (Cambridge University Press, 2020). He serves on the Topical Editor of Journal of Optics, the Executive Editor-in-Chief of Progress in Electromagnetics Research, the Editorial Board of Nanomaterials and the Nature's Scientific Reports.
Dr. Chen received the National Excellent Doctoral Dissertation Award in China (2008), the Zhejiang Provincial Outstanding Youth Foundation (2008), the National Youth Top-notch Talent Support Program in China (2012), the New Century Excellent Talents in University of China (2012), the National Science Foundation for Excellent Young Scholars of China (2013), and the National Science Foundation for Distinguished Young Scholars of China (2016). His research work on invisibility cloak was selected in Science Development Report as one of the representative achievements of Chinese Scientists in 2007.

Speech Title: Metamaterials for Invisibility Cloak and Super-scattering

Invisibility has been a topic of long-standing interest in both academia and industry, because of its potential for intriguing applications that have only appeared thus far in science fiction. The advent of metamaterials unprecedentedly ignited the enthusiasm toward pursuing invisibility cloaks. But despite two decades of research, the current technology of invisibility cloak is still facing serious bottlenecks. In this talk, I will address these challenges and review the recent experimental progress in metamaterial and invisibility cloak. In particular, I will discuss a deep-learning-enabled self-adaptive microwave cloak that exhibits a millisecond response time to an ever-changing incident wave and the surrounding environment, without any human intervention. Moreover, an optically transparent microwave cloak that simultaneously integrates longwave cloaking and shortwave transparency will be provided. Finally, I will discuss the experimental realization of super-scattering phenomenon. Instead of suppressing the scattering of an object to achieve invisibility, a super-scatterer can enable large absolute total cross section from subwavelength structures. The challenge to experimentally realize this super-scattering will also be addressed.
