What is it about?
This work explores how to control the movement of water waves inside oddly-shaped containers, like fuel tanks or reservoirs, using special designs on the container’s bottom. By creating "metabathymetry" - patterns inspired by advanced material science - we can make the waves behave as if the container was a simple rectangular box. This has potential to improve safety in transportation, energy systems, marine structures, and architecture by reducing dangerous wave motions and preserving stability. We combined computer simulations and real-world experiments to show how this works, making it easier to manage wave behaviors in practical situations.

Why is it important?
This research introduces a novel method for controlling water wave movement in irregularly shaped containers using specially designed structures called metabathymetry. It has important applications in fields like coastal engineering, fluid transport, or even liquid dampers on top of buildings, which help reduce building sway during high winds or earthquakes. By replicating regular wave behaviors in complex geometries, this approach offers safer and more efficient engineering solutions. It could improve structural stability, optimize resource use, and enhance safety in various systems, including energy harvesting and maritime design.
