Jin Chen received the B.Sc. and Ph.D. degrees in mechanics engineering from Jianghan University, Wuhan, China and Xi'an Jiaotong University, Xi'an, China in 2013 and 2017 respectively. From 2017 to prersent, Jin Chen is the PhD candidate in Beijig Institute of Technology focusing on gradient refractive index lens including typical GRIN lens such as Luneburg lens, Maxwell-fisheye lens and Mikaelian lens. His research interests covers photonic/phononic crystals, GRIN metamaterial, and transformation optics/acoustics. Proficient in theoretical design of GRIN lens, corresponding structural design, and experimental nearfield, far field test of electromagnetic field. He has authored or coauthored 14 papers, including Laser Photonics Reviews, Advanced Optical Materials, IEEE Transactions on Antennas and Propagation, ACS Applied Materials and Interfaces, Carbon, Composites Science and Technology, and Journal of Physics D: Applied Physics.
