The main thrust of our research in this area is to use the tailor-made material/structural properties to obtain extraordinary wave phenomena. We use metamaterials and photonic crystals as a platform to study non-Hermitian and topological physics. The combination of metamaterials and the extraordinary physics enabled by these materials/structures gives us the opportunity to achieve applications with radically new principles or optimal performance.
We have been supported by an Area-of-Excellence (AoE) fund and two Collaborative Research Funds (CRF), all from the Research Grants Council of Hong Kong. Towards applications, we have been supported by a Research Impact Fund (RIF) and have already translated part of our created knowledge to a successful startup company on acoustic metamaterials for noise absorption and attenuation.
The mission of this AoE is to set up an inter-disciplinary research platform that will generate fundamental knowledge and innovation in the field of wave functional materials.
This CRF project aims to investigate how non-Hermitian physics can be used to manipulate wave propagation in both optical and acoustic systems.
