Exploitation of Characteristic Modes Analysis and Additive Manufacturing Technologies for the Design of Metasurfaces and Beamsteering Antennas

Over the last decade, research has demonstrated that Characteristic Modes Analysis (CMA) provides significant physical insights into antenna behaviour, by describing currents and radiated fields by a rigorous modal representation and represents a powerful tool for antenna analysis and design. This analysis is particularly effective in cases where the platform hosting the antenna has dimensions comparable to the working wavelength since the CMA aims to transform the platform itself into an efficient radiator by using compact exciters. A proper design of these exciters in terms of number and placement allows to obtain radiators with beamsteering capabilities. The CMA can be also advantageously used to tailor metasurfaces that can transform the polarization of the field radiated by an antenna. The manipulation of the electromagnetic wavefront can be also achieved by properly design dielectric structures that can shape the field radiated by a single source to achieve multibeam and beam steering capability.

Simone Genovesi was born in Sarzana (SP) on January 18, 1978. He received the Laurea degree in Telecommunication engineering from the University of Pisa, Pisa, Italy, in 2003. He completed his PhD in the Department of Information Engineering in 2007 and the same year obtained the Italian habilitation for the profession of engineer. Since 2003 he has been collaborating with the Electromagnetic Communication Laboratory, Pennsylvania State University (Penn State), University Park. From 2004 to 2006 he has been a research associate at the ISTI institute of the National Research Council of Italy (ISTI-CNR) in Pisa. From 2010 to 2011 he has been an associate Researcher of the Institute for Microelectronics and Microsystem at the National Research Council (IMM-CNR), Agrate Brianza (Milano). During the period 2015-2017, he was several times a short-term Visiting Researcher at Grenoble Institute of Technology, Valence, France and at University Rovira I Virgili, Tarragona, Spain. In 2012 he joined as an Assistant Professor the Department of information Engineering University at University of Pisa where he is a Full Professor since 2024. In 2018 Simone Genovesi has been appointed Coordinator of the “Additive Manufacturing Crosslab” laboratory, founded in the framework of the Departments of Excellence funded by the Italian Ministry of Education, University and Research. Since 2024 Simone Genovesi is the Executive Director of the Crosslab project.
