Manipulation of Sound Properties by Acoustic Metasurface and Metastructure 精装 – 2016年8月17日
Dr. Jiajun Zhao received a BEng in Electronic Science and Engineering in 2012 from Nanjing University, China, and a PhD in Electrical and Computer Engineering in 2016 from the National University of Singapore (NUS). His research is focused on acoustic metamaterials and devices, and the effective medium theory. In 2014, he spent about 2 years as a research scholar at the Center for Nonlinear Dynamics at the University of Texas at Austin, working on computational fluid dynamics. His research has been supported by the NUS Research Scholarship and the NUS Presidential Fellowship, and acknowledged by the Chinese Government Award from the China Scholarship Council.
