ACE’09 – 5th Workshop on Advanced Computational Electromagnetics G Rome, Italy, January 12–14, 2009 Accademia dei Lincei, Palazzo Corsini, Via della Lungara, 10 Scientific Committee: Alain Bossavit (LGEP, France), Antonio DiCarlo (Università Roma Tre, Italy), Lauri Kettunen (TUT, Finland), Robert Kotiuga (Boston University, USA), Guglielmo Rubinacci (Università di Napoli Federico II, Italy), Francesco Trevisan (Università di Udine, Italy) (Italicized members form the Organizing Committee) Workshop Secretary: Mariella Vetrano (Consorzio CREATE) G Sponsors: Centro Linceo Interdisciplinare B. Segre, DiS (Università Roma Tre), DIEGM (Università di Udine), DIE (Università di Napoli Federico II) AIM AND SCOPE The practical premise of the ACE workshops is the recognized fact that the trend towards miniaturization, the increase of operating frequencies, and the emergence of new materials make conventional CAD tools less and less adequate. If progress is to be made, computational electromagnetism has to develop new ideas and integrate contributions from different scientific communities. ACE workshops were born as an open forum for such an endeavor. We aim at addressing open issues in computational electromagnetism in a broad perspective, gathering a reasonable number of speakers who shall present their views and discuss them at ease with a knowledgeable and reactive audience. In ACE’09, in particular, we focus mostly on complex responses of material media (covering both experimental analysis and mathematical modeling), basic formulations and discrete calculus, identification and inverse problems. TIME SCHEDULE ACE’09 is comprised of five sessions, each about four hours long (breaks included). The first session starts on Monday, January 12, at 9:00 am; the last one closes on Wednesday, January 14, at 1:00 pm. The time allotted to each contributed (invited ) talk is 20 (30) minutes plus 10 (15) minutes for discussion. 2 Session 1: Monday 12th, morning (chair: A. DiCarlo) 9:00 am Welcome address: A.
