Topological crystals to guide waves on the water surface

Topological crystals have the property of being conductive on their surface, but insulating in their volume which allows very efficient wave guidance by engineering the structure of these materials, generally arranged in a hexagonal symmetry, inspired by the graphene.

By controlling the waves thanks to an arrangement of cubes, researchers from FEMTO-ST institute, IRPHE (University of Aix-Marseille) and Imperial College of London have for the first time obtained this phenomenon with square symmetry. Published in Applied Physics Letters and promoted by the French National Centre for Scientific Research , this work underlines that the hexagonal arrangement is not the only one able to direct the waves in at least two directions.
