Metasurfaces: New Generation Building Blocks for Emerging Optics

Hosted By: Thin Films Technical Group

8 April 2021, 12:00 - 13:00 - Eastern Daylight Time (UTC - 04:00)

Light-matter interactions can be highly controlled via nanostructured thin films on the surface of objects. Indeed, a single-layer of designed and engineered subwavelength nanostructures, so-called metasurfaces, can resonantly couple to the incident light and manipulate the light’s behavior, in demand. Metasurfaces can reproduce the functions of bulk optics, and on occasions, can offer new functionalities that are not possible with conventional diffractive optics.

In this webinar hosted by the Thin Films Technical Group, Mohsen Rahmani, a Royal Society Wolfson Fellow and a UK Research and Innovation Future Leaders Fellow, from Nottingham Trent University will review his journey in employing metallic to dielectric and semiconductor metasurfaces to control the light intensity, frequency and propagation direction. In addition, Rahmani will discuss how metasurfaces can lead to several exciting applications, including night vision, flat optics and ultra-sensitive biochemical sensing. 

What You Will Learn:

  • What are metasurfaces
  • How metasurfaces can control the light-matter interactions
  • What applications metasurfaces can offer

Who Should Attend:

  • Active researchers in nanophotonics
  • Industrial stakeholders in nanoscale optical components


About the Presenter: Mohsen Rahmani, Nottingham Trent University

Mohsen Rahmani is an Associate Professor at Nottingham Trent University. His research activities span over light-matter interactions with various type of nanomaterials, e.g. metallic, dielectric and semiconductor nanoparticles, in the linear and nonlinear regime for applications in flat optics, near-infrared imaging, bio-sensing, etc. He obtained his PhD from the National University of Singapore in 2013, followed by postdoc fellowship at Imperial College London, and the Australian Research Council Early Career Fellowship at the Australian National University (ANU). In 2020, he moved to the Nottingham Trent University as a Royal Society Wolfson Fellow, and has recently been awarded by the UK Research and Innovation Fellowship. Rahmani has been invited to present his research findings at >30 international conferences and he has published more than 60 peer-reviewed journal papers, 28 of which have an impact factor > 10, with over 3k citations (H-index=31). He is the recipient of several prestigious awards and prizes including the Eureka Prize for Outstanding Early Career Academics (Australian Oscar of Science), Early Career Medal from the International Union of Pure and Applied Physics, and the Australian Optical Society Geoff Opat Award. He is an editorial board member of Applied Physics Letters Photonics and Opto-Electronic Advances. He has organised “Frontiers in Nanophotonics” workshop in Canberra in 2018 and has served as a committee member for five international conferences. In 2020, he was promoted to senior member of the Optical Society and IEEE.
