Sir John Pendry has worked at the Blackett Laboratory, Imperial College London, since 1981. He began his career in the Cavendish Laboratory, Cambridge, followed by six years at the Daresbury Laboratory where he headed the theoretical group. He has worked extensively on electronic and structural properties of surfaces developing the theory of low energy diffraction and of electronic surface states. Another interest is transport in disordered systems where he produced a complete theory of the statistics of transport in one dimensional systems. In 1992 he turned his attention to photonic materials and developed some of the first computer codes capable of handling these novel materials. This interest led to his present research, the subject of his lecture, which concerns the remarkable electromagnetic properties of materials where the normal response to electromagnetic fields is reversed leading to negative values for the refractive index
Nader Engheta is the H. Nedwill Ramsey Professor at the University of Pennsylvania in Philadelphia, with affiliations in the Departments of Electrical and Systems Engineering, Bioengineering, Materials Science and Engineering, and Physics and Astronomy. He received his BS degree from the University of Tehran, and his MS and Ph.D. degrees from Caltech. His current research activities span a broad range of areas including photonics, metamaterials, electrodynamics, nano-optics, graphene photonics, imaging and sensing inspired by eyes of animal species, microwave and optical antennas, and physics and engineering of fields and waves
Marco Sabbadini was born in Roma, Italy, in 1958. He received the Laurea degree in electronic engineering from the University of Rome La Sapienza, in 1983. From 1983 to 1988, he was with the Antenna Department, Alcatel Alenia Spazio Italy, Rome, Italy. In August 1988, he joined the European Space Agency as an Antenna Engineer in the Electrical System Department, European Space Research and Technology Center, Noordwijk, The Netherlands. Over these 30+ years he has been actively contributing to research and development in the area of electromagnetic modelling techniques and tools for antenna design fostering the introduction of new techniques and methodologies, not only on the electromagnetic side but also on the computational and software engineering ones. At the same time he has been actively working at innovative antenna solutions for space, promoting rethinking in some areas, like miniaturization and the application of new concepts.
