Abstract

This chapter retraces 50 years of personal research in microwaves, electromagnetic fields, and computational electromagnetics from an autobiographical perspective. It begins with early work on microwave ferrites at the RWTH Aachen and the University of Grenoble during the 1960s, and continues with theoretical and experimental research on planar and quasi-planar microwave circuits during the 1970s at the University of Ottawa. In the 1980s, my research focus began to shift progressively toward computational electromagnetics, and in the early 1990s at the University of Victoria it became the central theme of my work. Finally, the first decade of the second millennium brought novel materials with revolutionary properties and potential for innovative devices, requiring sophisticated techniques for modeling, measurement, and manufacturing at the nanometer scale. The activities and contributions of my research team during the past 50 years at the Universities of Aachen (Germany), Grenoble (France), Ottawa and Victoria (Canada), and finally at the A-STAR Institute of High-Performance Computing (Singapore), form the subject of this personal account.

Acknowledgments

I am indebted to all my former students, associates, colleagues, and friends who have accompanied me on my journey over the past 50 years, some for a brief time, others for a long stretch; I could not have succeeded without their precious contributions, ideas, and accomplishments. I cherish their inspiring participation and encouragement in my search for whatever lies beyond the horizon of perception; call it the essence, the deeper meaning, or simply the unknown.

I am also grateful to the peoples and governments of Germany, France, Canada, Italy, Switzerland, and Singapore for their precious support that enabled my education and career, and who provided my family and me with rich opportunities to live and grow.

Last, but not least, I am most indebted to Professor Iftikhar Ahmed who has initiated and coordinated this volume and the preceding special session at APEMC 2012 Singapore with considerable skill and dedication, and to Professor Zhizhang (David) Chen who has co-edited this project with him. It is a great honor and pleasure for me to consider it as the 50-years milestone of my research career. Finally, I want to extend my deep appreciation to all the authors who have contributed to this volume. Their talents and achievements are a source of pride for the entire electromagnetics community.
