Short Bio: 
Zuojia Wang received the B.E. degree in Electronic and Information Science in 2009, and the Ph.D. degree in Electronics Science and Technology in 2016, both from Zhejiang University, Hangzhou, China. From 2014 to 2016, he was a visiting scholar in Department of Mechanical & Industrial Engineering, Northeastern University, Boston. He has been an Associate Professor in 2017-2019, and Professor in 2019-2020, in School of Information Science and Engineering, Shandong University, China. In 2020, he joined Zhejiang University as a Professor of Hundred Talents Program. His current research interests include metamaterials, deformable electromagnetic media, chiral optics, antennas and nanophotonics.

Title: Research on Deformable Electromagnetic Metamaterials

Electromagnetic properties of metamaterials are determined by the geometry configuration of structures rather than the chemical constituent. Geometry deformation is one of the most direct method to achieve reconfiguration in macroscopic performance. In the talk, our recent progress on chiral light-matter interactions from meta-atom deformation is presented, including chiral absorbers, deflectors and polarizers. Deformable metamaterials based on origami techniques are also presented, including chirality switching in Miura-ori deformation, continuously tunable retroflection from metagratings and dispersion transition of origami waveguides.
