IET Harvey Prize Lecture to take place on 18 March 2019

Professor Mário G Silveirinha, a Professor at the University of Lisbon, Portugal, and Senior Researcher at Instituto de Telecomunicações was awarded the prestigious prize for his new approach and vision of how time-reversal symmetry can be broken with ‘mechanical motion’, by injecting a drift electric current into a material. His talk entitled: Time Reversal Symmetry Breaking with ‘Motion,’ will explore how his research aims to show how his ideas may enable the one-way propagation of microwave and terahertz waves totally immune to the undesired effects of back-scattering by obstacles, imperfections, and other deformations of the propagation path. This could open up a world of more compact electromagnetic isolators, novel light sources, better waveguides and more efficient energy harvesting. The prize will support a further five years of work in this area.

On receiving the award, Professor Silveirinha said: “I am extremely honoured. It is rather inspiring that Dr Arthur F. Harvey was himself one of the pioneers of nonreciprocal microwave devices, and I am thrilled that I will be able to build my own research on nonreciprocal and topological electromagnetics with the generous support of his Prize and contribute with innovative solutions for future technologies.”

Sir John O’Reilly, Chair of the IET’s Selection Committee for the Prize, said: “Professor Mário G. Silveirinha is awarded the A F Harvey Research Prize in recognition of his outstanding research achievements and as a pioneer in the field of near-zero index materials and photonics. This is a fundamental research area that will have important implications for applications such as mobile radio, radar, and optical fibre communication networks in the future.”
