Update: “Communication Using Intelligent Reflective Surfaces: Fundamentals and Recent Insights”

Abstract: The research on intelligent reflecting surfaces (IRS) is moving rapidly and much progress has been made since the 2019 keynote on “Communication Using Intelligent Reflective Surfaces: Myths and Realities”. In a nutshell, an IRS is a surface that can control how it interacts with radio waves; for example, how they are scattered or absorbed. This feature can be used to improve the communication conditions. This presentation will first recap the fundamentals, using the latest refined system description, and clarify the similarities and differences compared with the conventional repeater and relaying technologies. The talk will then convey recent insights into the two major research challenges: What is a convincing use case of IRS-technology, compared to competing technologies? How can control these surfaces in practice?
