Wave Propagation and Material Response inTime-Varying Media
June 10-11, 2025
Imperial College London, London, UK
-
Spatial metamaterials - materials spatially engineered to display specific properties - have changed how we manipulate light and sound, and are becoming ubiquitous in wave technology. The next frontier of fundamental and applied research is time-varying metamaterials, where functionalities emerge from changing the material properties in time.
A key unsolved problem is modelling the natural response of time-varying materials. Although mathematicians and physicists have approached this problem from the ideal and experimental perspectives, a concerted effort to combine these is required.
This workshop brings together experts from Physics and Mathematics to identify the key challenges and opportunities in the field, and discuss a roadmap for future research. The workshop is sponsored by the CNRS-Imperial International Research Center (IRC) Connect Fund and the Meta-4D project on next generation metamaterials.

CNRS - Imperial IRC for Transformational Science and Technology
CNRS, the largest fundamental science agency in Europe, and Imperial College London launched an institutional partnership in 2018, building on strong research collaborations in place between individual researchers and larger research groups, in particular those in Mathematics and quantitative sciences. In 2018 a joint CNRS-Imperial laboratory–the Abraham de Moivre International ResearchLab (IRL) in Mathematics, was established, which now serves as a hub for collaborations between the French and UK mathematics communities. This was CNRS’s first international joint research unit in the UK, and it has since hosted dozens of French mathematicians, organised workshops, published research papers and collaborated with other fields such as physics, computer science, biology, economics and social sciences.
A new CNRS-Imperial IRL, Ayrton Bleriot Engineering Lab, is due to be launched on 12 June, 2025.
This workshop has been funded from a Connect Fund from CNRS-Imperial IRC.

Meta-4D
Multiple, disruptive wave-based technologies (acoustic, elastic, radio-frequency, terahertz, and optical) would emerge if the response of the underlying materials could be modulated at will, varying throughout space and time.
META4D is a UKRI sponsored Programme grant that will simultaneously explore the fundamental physics of space-time-modulated materials and be the first to demonstrate their potential in realworld application.
