In this webinar hosted by the Photonic Metamaterials Technical Group, Mario Silveirinha from the University of Lisbon will provide an overview on current ongoing research on the area topological photonics, with particular emphasis to the consequences of nontrivial topologies in electromagnetic phenomena and their differences as compared to condensed-matter systems. Furthermore, the unique opportunities created by nonreciprocal systems with ill-defined topologies will be discussed. Finally, a novel non-Hermitian theory of electromagnetism will be introduced.

Subject Matter Level:

  • Intermediate - Assumes basic knowledge of the topic

What You Will Learn:

  • Topological photonics and their relationship with electromagnetism
  • Open questions regarding ill-defined topologies
  • Non-Hermitian theory of electromagnetism

Who Should Attend:

  • Early career researchers, postdoctoral fellows, graduate students and generally people interested in theoretical aspects in the emerging field of topological electromagnetism.


About the Presenter: Mário G. Silveirinha, University of Lisbon

Mário G. Silveirinha received a Licenciado degree in electrical engineering from the University of Coimbra in 1998 and a PhD in electrical and computer engineering (with a minor in applied mathematics) from the Instituto Superior Técnico, Technical University of Lisbon in 2003. Currently, he is a professor at the University of Lisbon and a senior researcher at Instituto de Telecomunicações. He was a visiting professor at the University of Pennsylvania in 2004-2005 and 2010-2011, and a Chercheur CNRS en Physique at University of Montpellier in 2017. Silveirinha was the 2018 recipient of the IET Harvey Engineering Research Prize “for contributions to electrodynamics of metamaterials and its applications to microwave components and devices”. He is also a Fellow of IEEE (2015), APS (2020) and OSA (2021). He is a founding editor of the APS journal Physical Review Applied. His research interests include electromagnetism, plasmonics and metamaterials, quantum optics, and topological effects (web.tecnico.ulisboa.pt/mario.silveirinha/).
