We find that a one-dimensional groove array can be equivalent to a negative water depth and excite unidirectional surface polaritons for water waves. We explain this phenomenon through theoretical analysis, numerical simulations, and experiments. This phenomenon shows that the propagation direction of water waves can be manipulated through such simple ...

Abstract We apply some general results for Hamiltonian systems, depending on the notion of signature of eigenvalues, to determine the circumstances under which collisions of imaginary eigenvalue for the linearized problem about a travelling water wave of permanent form are avoided or lead to loss of stability, up to non-degeneracy ...

By introducing concepts from transformation optics to the manipulation of water waves, we design and experimentally demonstrate two annular devices for concentrating waves, which employ gradient depth profiles based on Fabry-Pérot resonances. Our measurements and numerical simulations confirm the concentrating effect of the annular devices and show ...

This is a very important article, illustrating the high potential in the use of the boundary element method for the solution of wave diffraction- radiation problems. The equations for the wave structure interaction problem are discussed and for four different types of boundary conditions they are put into the boundary element formulation.

Asymptotic Integrability of Water Waves
Physical Review Letters, 1996Summary: The asymptotic integrability of the idealized water waves is formally established. Namely, it is shown that in the small amplitude, long wave limit there exists an explicit transformation which maps these equations to a system of two integrable equations.

In this paper, the author has formulated the gravity wave problem, considering a layer of incompressible, inviscid fluid with uniform depth in the gravity field, in terms of a variational principle. Based on the idea that a dominate mode exists for water waves of finite amplitude, using a variational method the author has derived a set of mode ...

Abstract Imagine you are standing by a pond on a still day. There is not a breath of wind and the water surface is absolutely flat. You pick up a large stone and heave it into the water. You know what will happen -the stone makes a splash at the place where it enters the water and then small waves travel out from that place in ...
