FD-04: Advanced preconditioning techniques for computational electromagnetics

Francesco P. Andriulli, Eric Michielssen

Sunday, July 19, 08:00 - 17:00

Abstract:

This course reviews the state of the art in effective preconditioning techniques for integral equations pertinent to the analysis of electromagnetic boundary value problems. The techniques covered permit the construction of rapidly convergent iterative solvers for electric and combined field integral equations and are a perfect complement to fast multipole and related accelerators.
Applications of these techniques range from antenna analysis to the characterization of microwave devices and circuits, the analysis of electromagnetic compatibility phenomena, and the synthesis of metamaterials. The course will cover theoretical and practical issues related to the development and implementation of several preconditioners, including those that derive from Calderon identities. Moreover, the course will detail the incorporation of the presented techniques into integral equation codes and their interaction with fast matrix-vector multiplication schemes. Finally, the course will demonstrate the usefulness of the techniques presented in in the above applications.

Biography:

Francesco P. Andriulli received the Laurea in electrical engineering from the Politecnico di Torino, Italy, in 2004, the MSc in electrical engineering and computer science from the University of Illinois at Chicago in 2004, and the PhD in electrical engineering from the University of Michigan at Ann Arbor in 2008. From 2008 to 2010 he was a Research Associate with the Politecnico di Torino. Since 2010 he has been with the École nationale supérieure des télécommunications de Bretagne (TELECOM Bretagne), Brest, France, where he is currently an Associate Professor. His research interests are in computational electromagnetics with focus on frequency- and time-domain integral equation solvers, well-conditioned formulations, fast solvers, low-frequency electromagnetic analysis, and simulation techniques for antennas, wireless components, microwave circuits, and biomedical applications.
Dr. Andriulli was the recipient of the best student paper award at the 2007 URSI North American Radio Science Meeting. He received the first place prize of the student paper context of the 2008 IEEE Antennas and Propagation Society International Symposium. He was the recipient of the 2009 RMTG Award for junior researchers and was awarded two URSI Young Scientist Awards at the International Symposium on Electromagnetic Theory in 2010 and 2013 where he was also awarded the second prize in the best paper contest. In addition, he co-authored another first prize conference paper (ICEAA 2009), two honourable mention conference papers (ICEAA 2011, URSI/IEEE-APS 2013), and other three finalist conference papers (URSI/IEEE-APS 2012, URSI/IEEE-APS 2007, URSI/IEEE-APS 2006). Moreover, he received the 2014 IEEE AP-S Donald G. Dudley Jr. Undergraduate Teaching Award and the 2014 URSI Issac Koga Gold Medal.
Dr. Andriulli is a member of Eta Kappa Nu, Tau Beta Pi, Phi Kappa Phi, and of the International Union of Radio Science (URSI). He serves as an Associate Editor for the IEEE Transactions on Antennas and Propagation, IEEE Antennas and Wireless Propagation Letters, and IEEE Access.

Eric Michielssen received his M.S. in Electrical Engineering (Summa Cum Laude) from the Katholieke Universiteit Leuven (KUL, Belgium) in 1987, and his Ph.D. in Electrical Engineering from the University of Illinois at Urbana-Champaign (UIUC) in 1992. He joined the faculty of the UIUC Department of Electrical and Computer Engineering in 1993, reaching the rank of Full Professor in 2002. In 2005, he joined the University of Michigan (UM) as Professor of Electrical Engineering and Computer Science. Since 2009, he directs the University of Michigan Computational Science Certificate Program.
Eric Michielssen received a Belgian American Educational Foundation Fellowship in 1988 and a Schlumberger Fellowship in 1990. Furthermore, he was the recipient of a 1994 International Union of Radio Scientists (URSI) Young Scientist Fellowship, a 1995 National Science Foundation CAREER Award, and the 1998 Applied Computational Electromagnetics Society (ACES) Valued Service Award. In addition, he was named 1999 URSI United States National Committee Henry G. Booker Fellow and selected as the recipient of the 1999 URSI Koga Gold Medal. He also was awarded the UIUC's 2001 Xerox Award for Faculty Research, appointed 2002 Beckman Fellow in the UIUC Center for Advanced Studies, named 2003 Scholar in the Tel Aviv University Sackler Center for Advanced Studies, selected as UIUC 2003 University and Sony Scholar; in 2011 he received the UM College of Engineering David E. Liddle Research Excellence Award. He is a Fellow of the IEEE (elected 2002) and a member of URSI Commission B.
Eric Michielssen served as the Technical Chairman of the 1997 Applied Computational Electromagnetics Society (ACES) Symposium (Review of Progress in Applied Computational Electromagnetics, March 1997, Monterey, CA), and served on the ACES Board of Directors (1998- 2001 and 2002-2003) and as ACES Vice-President (1998-2001). From 1997 to 1999, he was as an Associate Editor for Radio Science, and from 1998 to 2008 he served as Associate Editor for the IEEE Transactions on Antennas and Propagation.
Eric Michielssen authored or co-authored over one 160 journal papers and book chapters and over 300 papers in conference proceedings. His research interests include all aspects of theoretical and applied computational electromagnetics. His research focuses on the development of fast frequency and time domain integral-equation-based techniques for analyzing electromagnetic phenomena, and the development of robust optimizers for the synthesis of electromagnetic/optical devices.
