Talk Abstract:

Compressive sensing presents a new way of dealing withinformation retrieval and signal processing. Instead of thefine sampled version of a signal, computing a full set oftransform coefficients (although most of them are negligible),
it is possible to directly measure a compressed
representation of the signal thanks to the observation thatmost signals that arise in nature are sparse with relatively
few nonzero coefficients.
Compressive sensing exploits this sparsity allowing theinformation retrieval process (i.e., the reconstruction of theoriginal signal) from far fewer linear measurements than thesize of the signal. The task of recovering a sparse signal
from relatively few measurements then becomes theproblem of finding the sparsest solution of a severely
underdetermined linear system of equations. Although NPhard, it can be solved by means of efficient algorithms inmany useful circumstances.
The discovery of the “compressive sensing” paradigm has
led to the explosion of research worldwide in appliedmathematics, engineering, and computer science since its
impact goes far beyond compression and it applies
whenever acquiring data is difficult, dangerous, orexpensive. Thus, it has been rapidly exploited in several anddifferent ranges of practical electromagnetic problems
almost always leading to striking results that significantly
advance the state-of-the-art.
The objective of the short-course is therefore to provide theattendees an overview of CS as well as on its applications toelectromagnetics and, more specifically, to inversescattering. More in detail, after reviewing basics andfundamentals of CS, the course will focus on state-of-the-art
and mostly recently introduced CS-based techniques andalgorithms, discussing capabilities, limitations, andperspectives in Inverse Scattering and Microwave Imaging.
Applicative examples including exercises and speeches
regarding specific applications will corroborate thedeveloped concepts.

Biography:
Andrea Massa received the “laurea” degree in Electronic
Engineering from the University of Genoa, Genoa, Italy, in1992 and Ph.D. degree in EECS from the same university
in 1996. From 1997 to 1999, he was an AssistantProfessor of Electromagnetic Fields at the University ofGenoa. From 2001 to 2004, he was an Associate
Professor at the University of Trento. Since 2005, he has
been a Full Professor of Electromagnetic Fields at theUniversity of Trento.
At present, Prof. Massa is the director of the ELEDIA
Research Center with a staff of more than 40 researchers
located in the network of federated laboratories in Brunei,China, Czech Rep., France, Italy, Japan, Perù, Tunisia.
Moreover, he is Adjunct Professor at Penn StateUniversity (USA), Professor @ CentraleSupélec, andholder of a Senior DIGITEO Chair developed in cooperation between the Laboratoire des Signaux etSystèmes in Gif-sur-Yvette and the Department "Imagerieet Simulation for the Contrôle" of CEA LIST in Saclay(France). Prof. Massa serves as Associate Editor of the“IEEE Transaction on Antennas and Propagation”.
His research activities are mainly concerned with inverseproblems, analysis/synthesis of antenna systems andlarge arrays, radar systems synthesis and signalprocessing, system-by-design and material by design(metamaterials and reconfigurable materials), andtheory/applications of optimization techniques toengineering problems (telecoms., biology, medicine).
Prof. Massa published more than 270 scientificpublications on international journals, 350 in international
conferences (> 70 invited contributions). He has
participated to several technological projects in theEuropean framework (20 EU Projects) as well as at thenational level (>100 Projects/Grants).
