Professor Nader Engheta, University of Pennsylvania
4D Metaphotonics

Abstract:

In light-matter interaction the “space” and the “time” exhibit certain symmetry and duality. While these variables in electromagnetics are mathematically analogous in many aspects, their roles in wave propagation in material media naturally have certain differences. Exploring such space-time analogy in electromagnetic metamaterials provide exciting possibilities and new venues for controlling functionalities in light-matter interaction. Four-dimensional (4D) metamaterials are wave-based, material-based platforms in which some of the material parameters can vary with time (i.e., temporal inhomogeneities) in addition to (or instead of) varying in space (i.e., spatial inhomogeneities). Such 4D manipulation of waves in these structures lead to exciting wave phenomena. We have been investigating theoretically several scenarios for waves in such 4D metamaterials and have obtained various novel features that can provide potential applications in wave-based devices and components. In this presentation, I will present some of our most recent results on these topics.

About London Light:

The London Institute for Advanced Light Technologies was established in 2016 as a virtual centre between King’s College London, Imperial College London and University College London with a mission to provide an interdisciplinary and collaborative environment to explore new opportunities for growing research into light and its applications in the London area. London Light provides a framework for interactions with the photonic industry, training for PhD students and public outreach. The research focus is on new and emerging areas of photonics, including light for clean energy, light for biology and medicine, light for imaging metrology and sensors, light for data storage, manipulation and displays, advanced materials for nanophotonics, light for quantum technologies, and ultrafast photonics.
