Shaping a wireless future through intelligent metasurfaces

with George Eleftheriades


10 JANUARY 2022

In this episode of OJAP TALKS, George Eleftheriades, a leading figure in the field of metamaterials, talks with Mohsen Khalily, the Lead Guest Editor of the Special Section on Surface Wave and Metasurface Electromagnetic Engineering, about the latest advances in the technology of electromagnetic surfaces. Professor Eleftheriades goes through the appealing features of electromagnetic surfaces and reflects on their enabling role for the realization of a new realm of applications. He also sheds light on the exciting prospects of reconfigurable intelligent surfaces towards next-generation wireless networks and discusses emerging research frontiers including low-loss and broadband metasurfaces, active and adaptive metasurfaces, spatio-temporally modulated surfaces and new applications, and wideband wide-angle scanning metasurfaces. To young researchers exploring the field, Professor Eleftheriades says: "Think outside of the box for new ideas and opportunities and bring your fresh perspective into the field; follow your inspirations with passion and conviction and enjoy what you are doing."

Listen to the podcast and find answers to questions including the following:

  • What are electromagnetic surfaces and how can we classify them?
  • Why are electromagnetic surfaces important?
  • Can Reconfigurable Intelligent Surfaces (RIS) be a game-changer in wireless networks?
  • What are the main challenges of implementing RIS in a real-world scenario?


George Eleftheriades is a Professor in the Department of Electrical & Computer Engineering at the University of Toronto, Canada, where he holds the Canada Research Chair in Nano- and Micro-Structured Electromagnetic Materials and Applications. Mohsen Khalily is an Assistant Professor at 6G Innovation Centre, University of Surrey, UK.
