Adrianus Teunis de Hoop is a Dutch electrical engineer. De Hoop was born in Rotterdam, the Netherlands. He received his MSc-degree in Electrical Engineering and his PhD-degree in the Technological Sciences from Delft University of Technology, Delft, the Netherlands, both with the highest distinction. He served Delft University of Technology as an Assistant Professor, Associate Professor and Full Professor in Electromagnetic Theory and Applied Mathematics. Since 1996 he is Lorentz Chair Emeritus Professor in the Faculty of Electrical Engineering, Mathematics Computer Science of this University. In 1970 he founded at Delft the Laboratory of Electromagnetic Research, which has developed into a world-class center for electro-magnetics, having a huge impact on the world's electromagnetic community and on electromagnetic research and education in the Netherlands. De Hoop's research interests are in the broad area of wavefield modeling in acoustics, electromagnetics and elastodynamics. His interdisciplinary insights and methods in this field can be found in his seminal Handbook of Radiation and Scattering of Waves, with wavefield reciprocity serving as one of the unifying principles governing direct and inverse scattering problems and wave propagation in complex media. He spent a year as a Research Assistant with the Institute of Geophysics, University of California at Los Angeles, CA, USA, where he pioneered a modification of the Cagniard technique for calculating impulsive wave propagation in layered media, later to be known as the Cagniard–de Hoop method. This technique is considered as a benchmark tool in analyzing time-domain wave propagation. During a sabbatical leave at Philips Natuurkundig Laboratorium, Eindhoven, the Netherlands, he was involved in research on magnetic recording theory. Since 1982, De Hoop is on a regular basis Visiting Scientist with Schlumberger-Doll Research, formerly at Ridgefield, CT, now at Cambridge, MA, USA, where he contributes to research on geophysical applications of acoustic, electromagnetic and elastodynamic waves. Grants from the "Stichting Fund for Science, Technology and Research" supported his research at Delft University of Technology. He was awarded the 1989 Research Medal of the Royal Institute of Engineers in the Netherlands, the IEEE 2001 Heinrich Hertz Medal and the 2002 URSIBalthasar van der Pol Gold Research Medal. In 2003, Beatrix, Queen of the Netherlands appointed him Knight in the Order of the Netherlands Lion. De Hoop is a Member of the Royal Netherlands Academy of Arts and Sciences since 1989 and a Foreign Member of the Royal Flemish Academy of Belgium for Science and the Arts. He holds an Honorary Doctorate in the Applied Sciences from Ghent University, Belgium and an Honorary Doctorate in the Mathematical, Physical and Engineering Sciences from Växjö University, Växjö, Sweden. He is exploring a method for computing pulsed electromagnetic fields in strongly heterogeneous media with application to integrated circuits and a methodology for time-domain pulsed-field antenna analysis, design and optimization for mobile communication and radar applications. His avocation is playing the piano and performing choral music with the Rotterdam Philharmonic Choir.
