Biografia

Angelo Freni received his university degree (Laurea) in Electronics Engineering from the University of Florence in 1987. From 1990 to 2002 he was Assistant Professor of Electromagnetism at the Department of Electronic Engineering of the University of Florence, Italy. In 2002 he was appointed Associate Professor of Electromagnetism. In 1994, he was involved in research at the Engineering Department of the University of Cambridge, UK. From 1995 to 1999 he was also appointed Adjunct Professor at the University of Pisa. From 2000 he is on the committee of the PhD course in "remote sensing" of the University of Rome "La Sapienza." From November 2009 to October 2010 he was involved in research at the TNO Defence, Security and Safety, The Hague, The Netherlands. From 2010 he is visiting professor at the TU Delft University of Technology, Delft, The Netherlands.
His research interests include meteorological radar systems, radio wave propagation, numerical and asymptotic methods in electromagnetic scattering and antenna problems in microwave and millimeter band, and remote sensing. He has made original (and significant) contributions to the field of numerical methods, particularly concerning mode-matching techniques, integral equations, variational techniques and the finite element method. He has been responsible for several research projects for the ASI (Italian Space Agency) and the ESA (European Space Agency), concerning new antenna systems and the electromagnetic analysis of terrain scattering for modelling interferometer SAR simulators.
At present, he is collaborating with the Engineering Department of the University of Delft, (Delft, NL), the TNO Defence, Security and Safety, The Hague, NL, and the Ecole Polytechnique Fédérale de Lausanne, Lausanne, CH. Furthermore, he was the University of Florence Team Leader of the Antenna Centre of Excellence in the VI European Framework (2004-2007), and is deputy national delegate of the eight European COST Action on antennas (COST Action IC0603 "ASSIST").
Angelo Freni is the author of over 50 papers on international journals and of over 90 international conferences. He is a reviewer of several international scientific journals as the IEEE Transactions on Antennas and Propagation, Antennas and Wireless Propagation Letters, and the IEE Proc. Microwave, Antennas and Propagation. He is also Senior Member of IEEE.

Curriculum

Angelo Freni ha conseguito la Laurea in Ingegneria Elettronica presso l'Università di Firenze nel 1987. Dal 1990 è ricercatore presso la Facoltà di Ingegneria dell'Università di Firenze e dal 2002 professore associato di elettromagnetismo. Nel 1994 ha partecipato a ricerche presso l'Università di Cambridge, UK. Dal 1995 al 1999 è stato docente di Microonde presso la Facoltà di Ingegneria dell'Università di Pisa. Dal 2000 fa parte del Collegio Docenti del dottorato in Telerilevamento dell'Università di Roma La Sapienza e dal 2012 di quello di Ingegneria e Scienza dell'informazione dell'Università di Siena. Dal Novembre 2009 all'Ottobre 2010 ha svolto attività di ricerca presso il TNO Defence, Security and Safety, The Hague, The Netherlands. Dal 2010 è visiting professor al TU Delft University of Technology, Delft, The Netherlands.
Le sue attività di ricerca includono lo studio di sistemi radar per applicazioni meteorologiche ed il telerilevamento oltre allo sviluppo di metodi numerici ed asintotici per problemi di reirradiazione e di antenna. In tale attività di ricerca ha sviluppato tecniche innovative nell'ambito del metodo del mode-matching, della soluzione di equazioni integrali, di tecniche variazionali e del metodo degli elementi finiti applicato a strutture periodiche.
Durante la sua attività è stato/è responsabile scientifico di progetti di ricerca dell'Agenzia Spaziale Italiana e dell'Agenzia Spaziale Europea; progetti rivolti soprattutto allo studio di nuovi sistemi di antenne e all'analisi della reirradiazione da superfici rugose finalizzata alla simulazione di segnali provenienti da sistemi SAR interferometrici.
Al momento sta collaborando con l'Ecole Polytechnique Federale de Lausanne (Proff. Juan Mosig e Anja Skrivervik), la Chalmers University of Technology, Gothenburg, SE (Prof. Per-Simon Kildal) e l'University of Zagreb, Zagreb, HR (Prof. Zvonimir Sipus). Inoltre è stato coordinatore (2004-2007) per l'Università di Firenze dell'Antenna Center of Excellence nell'ambito del VI Programma Quadro della Comunità Europea ed è delegato nazionale (supplente) dell'ottavo European COST Action on antennas (COST IC0603).
Angelo Freni è autore di più di 60 articoli su riviste internazionali, più di 100 presentazioni a conferenze internazionali e nazionali e Senior Member dell'IEEE. E' revisore dell'IEEE Transactions on Antennas and Propagation, IEEE Microwave and Guided Wave Letters e IEE Proc. Microwave, Antennas and Propagation.

Biography

AngeloFreni received his university degree (Laurea) in Electronics Engineering from the University of Florence in 1987. From 1990 to 2002 he was Assistant Professor of Electromagnetism at the Department of Electronic Engineering of the University of Florence, Italy. In 2002 he was appointed Associate Professor of Electromagnetism and in 2014 he obtained the full professor qualification. In 1994, he was involved in research at the Engineering Department of the University of Cambridge, UK. From 1995 to 1999 he was also appointed Adjunct Professor at the University of Pisa. From November 2009 to October 2010 he was involved in research at the TNO Defence, Security and Safety, The Hague, The Netherlands. From 2010 he is visiting professor at the TU Delft University of Technology, Delft, The Netherlands.

His research interests include meteorological radar systems, radio wave propagation, numerical and asymptotic methods in electromagnetic scattering and antenna problems in microwave, sub-millimeter band, and remote sensing. He has made original (and significant) contributions to the field of numerical methods, particularly concerning mode-matching techniques, integral equations, variational techniques and the finite element method. He has been responsible for several research projects for the ASI (Italian Space Agency) and the ESA (European Space Agency), concerning new antenna systems and the electromagnetic analysis of terrain scattering for modelling interferometer SAR simulators. Furthermore, he was the University of Florence Team Leader of the Antenna Centre of Excellence in the VI European Framework (2004-2007), and was deputy national delegate of the eight European COST Action on antennas (COST Action IC0603 "ASSIST"). At present, he is collaborating with the Engineering Department of the University of Delft, (Delft, NL), the TNO Defence, Security and Safety, The Hague, NL, and the Ecole Polytechnique Fédérale de Lausanne, Lausanne, CH.

AngeloFreni is the author of over 60 papers on international journals and of over 100 international conferences. He is a reviewer of several international scientific journals as the IEEE Transactions on Antennas and Propagation, Antennas and Wireless Propagation Letters, and the IEEE Transactions on Terahertz Science and Technology. He is also Senior Member of IEEE.

Research experience:

- Meteorological radar systems, radiowave propagation, simulation models for meteorological radar. He took part in the Arno Project, sponsored by the Italian Council of National Research and the Italian Space Agency;

- Numerical and asymptotic methods in electromagnetic scattering and antenna problems. Concerning numerical methods he gave original contributions concerning mode-matching techniques, integral equations, variational techniques, method of moments, adaptive integral method and finite element method. Furthermore, he developed several algorithms that are currently integrated in the ADF-EMS framework supported by ESA, among which: the GAM/MoM rectangular horns and horns array modelling WARM, the multilayer Adaptive Integral Method (MLayAIM) for the analysis of very large microstrip arrays, the multilevel fast Physic Optics algorithm (MLFPO) for the fast computation of the scattering from large and complex metallic objects;

- Design of large arrays, reflectarrays and radial line slot arrays;

-Remote sensing, satellite sensors modelling, numerical models for the evaluation of the electromagnetic scattering from rural and urban areas;

- He was also involved in a few medical research projects about heart rate variability and functional severity of congestive heart failure secondary to coronary artery disease.
