Summary
Surface water waves can become spatially localized over rough bottoms due to multiple scattering and interference. This phenomenon, analogous to frozen light, leads to exponential transmission loss and cooperative behavior.
Area of Science:
- Fluid dynamics
- Wave propagation physics
Background:
- Surface water waves are crucial in coastal and oceanographic studies.
- Understanding wave interaction with rough topography is complex.
- Previous studies explored wave localization in optical systems.
Purpose of the Study:
- Investigate surface water wave propagation over rough bottoms.
- Analyze wave localization via multiple scattering theory.
- Explore the analogy with frozen light phenomena.
Main Methods:
- Applied multiple scattering theory.
- Utilized wave interference principles.
- Employed a graphic method for visualization.
Main Results:
- Demonstrated spatial localization of surface water waves.
- Observed exponential decay in wave transmission when localized.
- Identified cooperative behavior in wave propagation.
Conclusions:
- Surface water waves can exhibit spatial localization over rough topography.
- The phenomenon aligns with predictions from similar optical systems.
- A distinct phase state in wave propagation is illustrated.
