Andrea Alù is the Founding Director and Einstein Professor at the Photonics Initiative, CUNY Advanced Science Research Center, St Nicholas Terrace, NY, USA. He received his Laurea (2001) and PhD (2007) from the University of Roma Tre, Italy, and, after a postdoc at the University of Pennsylvania, he joined the faculty of the University of Texas at Austin in 2009, where he was the Temple Foundation Endowed Professor until 2018. His research interests span over metamaterials, plasmonics, nano-optics, electromagnetics and acoustics. Dr. Alù is a Fellow of NAI, IEEE, AAAS, OSA, SPIE and APS, and has received several scientific awards, including the IEEE Kiyo Tomiyasu Award, the Vannevar Bush Faculty Fellowship from DoD, the ICO Prize in Optics, the NSF Alan T. Waterman award, the OSA Adolph Lomb Medal, and the URSI Issac Koga Gold Medal. Nader Engheta is the H. Nedwill Ramsey Professor of Electrical and Systems Engineering at the University of Pennsylvania, Philadelphia, Pennsylvania, USA. He received the BS degree (with highest rank) in electrical engineering from the University of Tehran, the MS degree in electrical engineering and the Ph.D. degree in electrical engineering (with a minor in physics) both from the California Institute of Technology (Caltech). After spending one year as a Postdoctoral Research Fellow at Caltech and four years as a Senior Research Scientist at Kaman Sciences Corporation's Dikewood Division in Santa Monica, CA, he joined the faculty of the University of Pennsylvania, where he rose through the ranks and is currently H. Nedwill Ramsey Professor of Electrical and Systems Engineering. He is also a member of the Mahoney Institute of Neurological Sciences at the University of Pennsylvania, and holds secondary appointments in the Department of Bioengineering and the Department of Physics and Astronomy at University of Pennsylvania. He was the graduate group chair of electrical engineering from July 1993 to June 1997. Andrea Massa is a Full Professor of Electromagnetic Fields at the University of Trento, Italy, and the Director of the ELEDIA Research Center network of federated laboratories with more than 150 researchers located in Brunei, China, Czech, France, Greece, Italy, Japan, Peru, and Tunisia. Moreover, he is holder of a Chang-Jiang Chair Professorship at UESTC (Chengdu, China), Visiting Research Professorhip at the University of Illinois at Chicago (Chicago, USA), Distinguished Visiting Professorship at Tsinghua University (Beijing, China), Visiting Professorship and IAS Distinguished Scholar at Tel Aviv University (Tel Aviv, Israel), and Professorship at CentraleSupélec (Paris, France). His research activities are mainly concerned with inverse problems, antenna analysis/synthesis, radar systems and signal processing, cross-layer optimization and planning of wireless/RF systems, system-by-design and material-by-design (metamaterials and reconfigurable-materials), and theory/applications of optimization techniques to engineering problems (communications, medicine, and biology). Giacomo Oliveri is an Associate Professor at the Department of Civil, Environmental, and Mechanical Engineering, University of Trento, and a Board Member of the ELEDIA Research Center. He received his BS and MS degrees in Telecommunications Engineering and a PhD in Space Sciences and Engineering from the University of Genoa, Italy, in 2003, 2005, and 2009 respectively. He is currently also an Adjunct Professor at CentraleSupélec (Paris, France) where he is a member of the Laboratoire des signaux et systèmes. His research work is mainly focused on electromagnetic direct and inverse problems, metamaterials analysis and design, and antenna array synthesis.
