| Abstract: The scientific foundations of electromagnetic theory and its modern offspring, electromagnetic field simulators, are rooted in ideas about the nature of light that evolved over thousands of years, and pre-date the magnificent theoretical framework of Maxwell. Over three hundred years ago, Huygens formulated a time-and space-discrete model of light propagation, the concept of a Green's function, and the representation of a general field solution in terms of basis functions, known today as the general method of moments. Recent advances in digital computers, digital signal processing and object-oriented programming have unleashed these powerful ideas and opened exciting possibilities in engineering design. In particular, time domain simulators such as MEFiSTo (Multi-purpose Electromagnetic Field Simulation Tool) are able to emulate the evolution of electroma- gnetic fields in space-time, solve coupled physical processes driven by electromagnetic fields (such as thermal and mass diffusion) and even synthesize structures directly through monochromatic field injection. Fields, networks, circuits, and devices can be connected and solved globally using the SPICE-EM-bed framework of MEFiSTo. During this presentation, MEFiSTo will be used extensively to demonstrate these modeling features and to show how the fundamental field concepts of the past have been transfigured into a modern design tool for RF-to-optical, high-speed digital, and EMC engineering applications. |
| Biography: Dr. 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. In 1969 he joined the Department of Electrical Engineering, the University of Ottawa as a Faculty member.
