Mário Silveirinha awarded £350,000 research grant to ‘break’ time-reversal symmetry with mechanical motion

Professor Mário Silveirinha, from the University of Lisbon and researcher at IT is the winner of the £350,000 IET A. F. Harvey Engineering Research Prize. He was chosen from high-calibre candidates from across the world as a result of his new approach and vision of how time reversal symmetry can be broken with ‘mechanical motion’, such as by injecting a drift electric current into a material.

The funding will support a further five years of work with the aim of showing how such solutions 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.

Professor Silveirinha, said: “I am extremely honoured to receive the IET A. F. Harvey Engineering Research Prize. 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: “Prof. 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.”

The IET’s A F Harvey Research Prize, worth £350,000, is named after Dr. A. F. Harvey who bequeathed a generous sum of money to the IET for a trust fund to be set up in his name for the furtherance of scientific research into the fields of medical, microwave, laser or radar engineering.

Prof. Mário Silveirinha will present a prize lecture on his research at IET London: Savoy Place on 18 March 2019.
