Abstract: Time domain electromagnetic simulators based on the Transmission Line Matrix (TLM) method provide advanced features for multi-level modeling of analog and high-speed circuits. These features include sophisticated boundary models for diakoptics and coupled field/circuit and multi-physics simulations, import/export and external control capabilities enabling Space Mapping and surrogate generation for fast optimization, and inter-cell models of complex materials, such as metamaterials and frequency-dispersive media. The underlying principles of these features will be explained, and typical application scenarios will be demonstrated during the presentation.

Biography: Wolfgang J.R. Hoefer received the Dipl.-Ing. degree in Electrical Engineering from the Technische Hochschule Aachen, Germany, in 1965, and the D. Ing. degree from the University of Grenoble, France, in 1968.

During the academic year 1968/69 he was a Lecturer at the Institut Universitaire de Technologie de Grenoble and a Research Fellow at the Institut National Polytechnique de Grenoble, France. In 1969 he joined the Department of Electrical Engineering, the University of Ottawa, Canada, where he was a Professor until March 1992. Since April 1992 he holds the NSERC Industrial Research Chair in Radio Frequency Engineering in the Department of Electrical and Computer Engineering, the University of Victoria, Canada.

During several sabbatical leaves he has been Visiting Scientist and Professor at the following establishments: the Space Division of AEG-Telefunken in Backnang, Germany (now ATN), the Electromagnetics Laboratory of the Institut National Polytechnique de Grenoble, France, the Space Electronics Directorate of the Communications Research Centre in Ottawa, Canada, the University of Rome "Tor Vergata", Italy, the University of Nice – Sophia Antipolis, France, the Technical University of Munich, the Ferdinand Braun Institute for High Frequencies, Berlin, the Gerhard Mercator University in Duisburg, Germany, the Georgia Institute of Technology, Atlanta, and the University of Perugia, Italy.

His research interests include numerical techniques for modeling electromagnetic fields and waves, computer aided design of microwave and millimeter wave circuits, microwave measurement techniques, and engineering education. He serves regularly on the Technical Program Committees of IEEE-MTT and AP Symposia, is the Co-Chair of the MTT Technical Committee on Field Theory (MTT-15), and the co-founder and Managing Editor of the International Journal of Numerical Modelling. He serves on the editorial boards of the IEEE-MTT Transactions, Proceedings of the IEE, the International Journal of Microwave and Millimeter-Wave Computer Aided Engineering, Electromagnetics, and the Microwave and Optical Technology Letters. He was Associate Editor of the IEEE-MTT Transactions from 1998-2000, an "Invited Lansdowne Lecturer" of the University of Victoria, B.C., in 1989, and was awarded the "Peter B. Johns Prize" for the best paper published in the International Journal of Numerical Modelling in 1990. He is a Distinguished Microwave Lecturer of the IEEE MTT Society for 2005 – 2007 and a recipient of the IEEE MTT Distinguished Educator Award. He was elected Fellow of the IEEE for "contributions to the modeling and design of passive microwave and millimeter-wave circuits" in 1991, Fellow of the British Columbia Advanced Systems Institute (BC-ASI) in 1992, and Fellow of the Royal Society of Canada in 2003.
