Biography

Angelo Freni received the Laurea (Doctors) degree in Electronics Engineering from the University of Florence in 1987. Since 1990 he is with the Department of Electronic Engineering of the University of Florence, Italy, first as Assistant Professor and from 2002 as Associate Professor of electromagnetism. From 1995 to 1999 he has also been an Adjunct Professor at the University of Pisa, and from 2012 a Visiting Professor at the TU Delft University of Technology, Delft, The Netherlands.

During 1994, he was involved in research at the Engineering Department of the University of Cambridge, UK, concerning the extension and the application of the finite element method to the electromagnetic scattering from periodic structures. Between 2009 and 2010 he also spent one year as a researcher at the TNO Defence, Security and Safety, The Hague, The Netherlands, working on the electromanetic modeling of kinetic inductance devices and their coupling with array of slots in THz range.

His research interests include meteorological radar systems, radiowave propagation, numerical and asymptotic methods in electromagnetic scattering and antenna problems, electromagnetic interaction with moving media and remote sensing. In particular, part of his research concerned numerical techniques based on the integral-equation, with focus on domain-decomposition and fast solution methods.
