C. Zou, Mechanically tunable dielectric resonator metasurface at visible frequencies, 25th February 2016.



Recent years have seen significant advances in light manipulation with ultrathin planar metasurfaces. The underlying mechanism is spatially varying phase discontinuity introduced by subwavelength resonators. Metallic resonators have commonly been used as a core component in metasurfaces so far. Recently we have shown that it is possible to replace metallic resonators with dielectric counterparts made of low-loss materials to increase the efficiency significantly. In this talk, I will introduce our latest research on mechanically tunable dielectric resonator metasurfaces at visible frequencies. This talk will also cover a general background of optical metasurfaces, including its principles and applications.



Chengjun Zou received his Bachelor of Engineering Degree in Electrical and Electronic Engineering (First Class Honours) from the University of Adelaide in 2012. He has started his PhD program in the Applied Electromagnetics Group of the School of Electrical and Electronic Engineering in 2013. His research interests includes dielectric resonator antennas, nano-optics, and plasmonics.
