The transfer matrix method reveals how water waves propagate over periodic and random bottoms. Anderson localization was observed in random bottoms, matching experimental data.

Area of Science:

  • Fluid dynamics
  • Wave propagation
  • Condensed matter physics

Background:

  • Understanding water surface wave behavior over complex geometries is crucial in oceanography and coastal engineering.
  • Previous studies have explored wave propagation but lacked detailed analysis of random bottom effects.

Purpose of the Study:

  • To investigate water surface wave propagation over one-dimensional periodic and random bottoms.
  • To analyze the band structure for periodic bottoms and compare it with transmission results.
  • To observe and explain the Anderson localization phenomenon in random bottom scenarios.

Main Methods:

  • Utilizing the transfer matrix method for theoretical analysis.
  • Calculating band structures for periodic bottom configurations.
