Wavefront engineering using Plasmonic Metasurfaces
 
 
 
Abstract
Benefitting from the flexibility in engineering their optical responses, metamaterials have been used to achieve control over the propagation of light to an unprecedented level, leading to highly unconventional and versatile optical functionalities in comparison to their natural counterparts. Recently the emerging field of meta-surfaces consisting of a monolayer of artificial atoms has offered attractive functionalities of shaping the wave front of light by introducing an interfacial abrupt phase discontinuity. In this talk, I will talk about our recent works on optical metasurfaces consisting of an array of plasmonic rods with spatially varying orientations, where the local phase profile is determined by the orientation of each rod. In particular, I will focus on three examples of device applications: a dual polarity metalens that can functions either a convex or a concave lens,  helicity switchable unidirectional excitation of surface plasmon polaritons, and 3D computer generated hologram.
 
Biography
Shuang Zhang is a professor in the school of Physics & Astronomy, University of Birmingham, UK. He received BS in Physics from Jilin University, MS in Physics from Northeastern University, and Ph.D in Electrical Engineering from the University of New Mexico.
From 2005 to 2006, he was a Postdoctoral Research Fellow at the University of Illinois at Urbana-Champaign, and from 2006 to 2010, he was first a Postdoctoral Research Fellow and later an Assistant Research Engineer at the University of California Berkeley. In March 2010, he took the position of Reader in the School of Physics & Astronomy, University of Birmingham, and was promoted to professor in 2013.

Professor Zhang is the recipient of IUPAP (International Union of Pure and Applied Physics) Young Scientist Prize in Optics, 2010 for his research on optical metamaterials.  He serves as an editor of <Light:Science & Application> - a new journal launched by Nature and Changchun Institute of Optics and Fine Mechanics.
