Electromagnetic devices and systems are at the heart of technological advances driving and changing many areas of science and engineering including efficient energy management, biomedical electronics, communications and computing, and even environmental monitoring and civil design. The common denominator of these systems is that they are electrically large, have a wide dynamic range of frequency of operation, their device components are geometrically intricate with dimensions varying by orders of magnitude, and finally their designs require many repetitions of characterizations with different parameters. The research field of computational electromagnetics enables accurate, efficient, and robust numerical modeling and characterization of such systems. This is a challenging task because the common characteristics listed above translate into large matrix systems with millions (if not billions) of unknowns to be solved for, multi-scale discretizations, and ill-conditioned equations followed by prohibitively long executions times. To address these challenges, my research group at KAUST has been developing efficient, stable, and accurate time marching schemes for solving integral equations of electromagnetics. Technical part of my presentation will focus on the formulation and implementation of these schemes and provide numerical results demonstrating their accuracy and efficiency. I will conclude my talk with a brief summary my future research plans and my teaching activities at KAUST. 

Hakan Bagci is an Assistant Professor in the Division of Computer, Electrical, and Mathematical Sciences and Engineering. Previously, from 2007 to 2009, he worked as a Research Fellow at the Radiation Laboratory, University of Michigan, Ann Arbor, US. He earned his master’s and doctoral degrees in Electrical and Computer Engineering from the University of Illinois, Urbana-Champaign, USA, in 2003 and 2007, respectively. He received his bachelor’s degree in Electrical and Electronics Engineering from the Bilkent University, Ankara, Turkey in 2001. His research interests are in the field of theoretical and applied computational electromagnetics. He focuses on developing acceleration engines, preconditioning techniques, and hybridization methods, which render time and frequency domain integral equation solvers applicable to the analysis of electrically large and multi-scale real-world problems. Hakan Bagci is the recipient of the 2008 International Union of Radio Scientists (URSI) Young Scientist Award and the 2004–2005 Interdisciplinary Graduate Fellowship from the Computational Science and Engineering Department at the University of Illinois, Urbana-Champaign. His paper titled “Fast and rigorous analysis of EMC/EMI phenomena on electrically large and complex structures loaded with coaxial cables” was one of the three finalists (with honorable mention) for the 2008 Richard B. Schulz Best Transactions Paper Award given by the IEEE Electromagnetic Compatibility Society. He authored and co-authored five finalist papers in the student paper competitions at the 2005, 2008, and 2010 IEEE Antennas and Propagation Society International Symposiums and 2013 Applied Computational Electromagnetics Society Conference. He has been recently elevated to the grade of IEEE Senior member.
