Small cells, massive MIMO, millimeter-wave communications are three fundamental technologies that will spearhead the emergence of 5G wireless networks – Their advantages are undeniable. The question is, however, whether these technologies will be sufficient to meet the requirements of future wireless networks that integrate communications, sensing, and computing in a single platform.

Wireless networks, in addition, are rapidly evolving towards a software-defined design paradigm, where every part of the network can be configured and controlled via software. In this optimization process, however, the wireless environment itself – the medium or channel – is generally assumed uncontrollable and often an impediment to be reckoned with. For example, signal attenuation limits the network connectivity, multi-path propagation results in fading phenomena, reflections and refractions from objects are a source of uncontrollable interference.

Recently, a new concept called reconfigurable intelligent surfaces (RISs) has emerged wherein every environmental object is coated with man-made intelligent surfaces of configurable electromagnetic materials. These materials would contain integrated electronic circuits and software that enable control of the wireless medium. Thus, RISs enable telecommunication operators to sculpt the very medium that comprises the network. With the aid of RISs, wireless networks will not be designed anymore to adapt themselves to the environment, but the environment will become part of the optimization space. As such, RISs have the potential to fundamentally change how wireless networks are designed and usher in that hoped-for wireless future. But, RISs are not currently well-understood.


Marco Di Renzo received the Laurea (cum laude) and the Ph.D. degrees in electrical engineering from the University of L’Aquila, L’Aquila, Italy, in 2003 and in 2007, respectively, and the Habilitation à Diriger des Recherches (Doctor of Science) degree from University Paris-Sud, France, in 2013. He has held research and academic positions in Italy at the University of L’Aquila, in the United States at Virginia Tech, in Spain at CTTC, and in the United Kingdom at The University of Edinburgh. Since 2010, he has been a CNRS Associate Professor (“Chargé de Recherche Titulaire CNRS”) in the Laboratory of Signals and Systems of Paris-Saclay University—CNRS, CentraleSupélec, University Paris Sud, France. He is a Distinguished Visiting Fellow of the Royal Academy of Engineering, U.K. He is a co-founder of the university spin-off company WEST Aquila s.r.l. Italy. He is a recipient of several awards, including Best Paper Awards at IEEECAMAD (2012 and 2014), IEEE-VTCfall (2013), IEEE-ATC (2014), IEEE ComManTel (2015), the 2013 Network of Excellence NEWCOM# Best Paper Award, the 2013 IEEE-COMSOC Best Young Researcher Award for Europe, Middle East and Africa (EMEA Region), the 2015 IEEE Jack Neubauer Memorial Best System Paper Award, and the 2015-2018 CNRS Award for Excellence in Research and in Advising Doctoral Students. Currently, he serves as an Editor of the IEEE COMMUNICATIONS LETTERS and IEEE TRANSACTIONS ON COMMUNICATIONS, where is the Editor for Heterogeneous Networks Modeling and Analysis of the IEEE Communications Society. He is a Senior Member of the IEEE (COMSOC and VTS) and a Member of the European Association for Communications and Networking (EURACON). He is a Distinguished Lecturer of the IEEE Vehicular Technology Society. He is the Project Coordinator of the H2020 projects ITN-5Gwireless and ITN-5Gaura and he is or has been a Principal Investigator of the EU-funded projects ITN-GREENET, ITN-CROSSFIRE, IAPP-WSN4QoL, IAPP-SmartNRG, RICE-CASPER, and of the ANR-funded (French Science Foundation) project SpatialModulation. He is the representative for CNRS and Paris-Saclay University of the COST Action IRACON.
