DST Keynote: Digital Twins for Wireless Meta-Surfaces

Speakers: Majid Moradikia and Seyed (Reza) Zekavat, Worcester Polytechnic Institute (WPI)

Title: An Introduction to Digital Twins for Meta-Surface Empowered Wireless Networks


To support the stringent requirements of the emerging applications, such as augmented reality and brain-computer interface, wireless-based digital twin technology has been emerged recently. Digital twining creates a virtual representation of a wireless network at Edge devices. Edge-enhanced digital twining at wireless networks supports the creation of Intelligent Radios that facilitate real-time intelligent radio resource management. This talk aims to introduce the potentials of reconfigurable intelligent surface (RIS) technology equipped with digital twining for ultra-reliable low-latency communication (URLLC).

RIS technology have become a focal point of research due to their advantages to enhance the physical layer security, reliability, energy-efficiency, and coverage by smart reconfiguration of the wireless environment that is enabled by Digital Twin concept. The RIS panels have two-dimensional (2D) structure that are nearly passive and composed of metamaterial with macroscopic programmable physical characteristics. In this talk, we present a comprehensive review over the state-of-the-art on RIS families, with emphasis on their operating principles from the viewpoints of both physics and communications, their passive beamformer design, and, ML-enabled RIS wireless networks. We will also discuss the compatibility of reinforcement learning (RL) with RISs to constantly control the dynamic nature of wireless propagation while reaching a seamless integrated framework for Communication, sensing, and computation. Last but not the least, we will discuss the research opportunities of amalgam of RISs with other emerging technologies such as edge computing and Quantum machine learning (QML) to satisfy the ambitious goals of WDT.
