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. More specifically, the team designs, fabricates and characterizes new materials that can manipulate light and sound in ways not known before.
New and improved existing techniques are developed for the realization of these new materials. These wave functional materials are then used to achieve interesting and unusual effects that are not possible with natural materials and explore and realize potential applications of these new materials.
Topological control of light and sound waves are completely new phenomena. Upper Panel shows a topological one-way edge state on an acoustic topological phononic crystal. Metamaterials can have optical properties not found in nature. The bottom panel shows a metamaterial with index ellipsoids not centered about zero momentum.
