Walter Fuscaldo (S’15–M’18) received the M.Sc. (cum laude) degrees in Telecommunications Engineering from Sapienza University of Rome, Rome, in 2013. In 2017, he received the Ph.D. degree (cum laude and with the Doctor Europaeus label) in Information and Communication Technology (Applied Electromagnetics curriculum) from both the Department of Information Engineering, Electronics and Telecommunications (DIET) and the Institut d’Électronique et de Télécommunications de Rennes (IETR), Université de Rennes 1, Rennes, France, under a cotutelle agreement between the institutions. In 2014, 2017, and 2018, he was a Visiting Researcher with the NATO-STO Center for Maritime Research and Experimentation, La Spezia, Italy. In 2016, he was a Visiting Researcher with the University of Houston, Houston, TX, USA. Since July 2017, he was a Postdoc Researcher at Sapienza University of Rome, and since July 2020, he joined the Institute for Microelectronics and Microsystems (IMM), Rome, Italy, as a Research Fellow of the National Research Council of Italy. His current research interests include propagation of leaky waves, surface waves and surface plasmon polaritons, analysis and design of leaky-wave antennas and reconfigurable metasurface antennas, generation of localized electromagnetic waves, graphene electromagnetics, and THz devices.
