Laszlo Solymar is Emeritus Professor of Applied Electromagnetism at the University of Oxford and Visiting Professor and Senior Research Fellow at Imperial College, London. He graduated from the Technical University of Budapest in 1952 and received the equivalent of a PhD in 1956 from the Hungarian Academy of Sciences. In 1956, he settled in England where he worked first in industry and later at the University of Oxford. He conducted research on antennas, microwaves, superconductors, holographic gratings, photorefractive materials, and metamaterials. He has held visiting professorships at the Universities of Paris, Copenhagen, Osnabrück, Berlin, Madrid, Budapest, and since 2000 Imperial College, London. He has published 8 books and over 250 papers. He has been a Fellow of the Royal Society since 1995, and re received the Faraday Medal of the Institution of Electrical Engineers in 1992. The late Donald Walsh was an Emeritus fellow of Oriel College, Oxford. He first worked for seven years at the Mullard Radio Valve Co, developing photo cells and flash tubes, then for about the same period at the Services Electronics Research Labs (SERL) on travelling wave tubes, klystrons and TR switches. He came to the Department of Engineering Science, Oxford in 1956 as a research fellow to help the newly appointed Reader in Electrical Engineering start a research group in microwave electronics, and later became a lecturer and college fellow. Richard R. A. Syms has been Head of the Optical and Semiconductor Devices Group in the EEE Department, Imperial College London, since 1992 and Professor of Microsystems Technology since 1996. He graduated in Engineering Science at Oxford University in 1979, and obtained a DPhil in 1982, also from Oxford. He carried out postgraduate work at University College London, Oxford University, and the Rutherford Appleton Laboratory before moving to Imperial. He has published around 180 journal papers, 100 conference papers and 2 books on holography, guided wave optics, electromagnetic theory, metamaterials, magnetic resonance imaging, and micro-electro-mechanical systems (MEMS), and has 18 granted patents. In 2001, he co-founded the Imperial College spin-out company Microsaic Systems. He is an Associate Editor for the Journal of Microelectromechanical Systems. He is a Fellow of the Royal Academy of Engineering, the Institute of Physics, and the Institute of Electrical Engineers.
