Electromagnetics in a Complex World : Challenges and Perspectives

This monograph contains the ceremonials and proceedings of the Workshop/Minisymposium on "Electromagnetics in a Complex World: Challenges and Perspectives", convened at the University of Sannio, Benevento, Italy from February 20-21, 2003, in connection with the bestowal of an honorary Laurea degree on Professor Leopold B. Felsen. The various contributions from scientists and engineers in academy and industry address diverse problems in electromagnetics, either on a broad scale or in particular specialties. The wide-ranging topics and techniques, analytic models (with phenomenologies) and numerical simulations - motivated by actual or potential applications to real-world problems - are intended to stimulate interdisciplinary exchange.

Felsen. The symposium was co-organized by Professors Innocenzo M. Pinto and Vincenzo Galdi, in consul­ tation with Professor Felsen. The University of Sannio is a recently installed fast-growing university enrolling about 6,500 undergraduate and graduatestu­ dents in its various programs (Law, Economics, Engineering, Sciences). The College of Engineering presently comprises 50 faculty members and about 1,500 students. The degree bestowal ceremony took place in the morning of February 20, 2003, and is documented (in English) in its entirety here in Part VI of these Proceedings (because of the international character of this two-day event, the program booklet provided for attendees of the degree award ceremony was printed in Italian and English). After a brief greeting by Prof. Aniello Cimitile, the President of the University of Sannio, Professor Pinto, who had originally proposed Prof. Felsen's nomination, delivered (in Italian) a detailed Laudatio, a laudatory discourse on the nominee's accomplishments and per­ sonality. This was followed by the nominee's Lectio, a retrospective covering his professional life as well as his social and cultural background, presented (in English) in a mixed style laced with humor, and comprising prose, verses, visuals, and photographs.
