Trapping of water waves by submerged plates using hypersingular integral equations
@article{Parsons1995TrappingOW, title={Trapping of water waves by submerged plates using hypersingular integral equations}, author={N. F. Parsons and Paul A. Martin}, journal={Journal of Fluid Mechanics}, year={1995}, volume={284}, pages={359 - 375} }
The trapping of surface water waves by a thin plate in deep water is reduced to finding non-trivial solutions of a homogeneous, hypersingular integral equation for the discontinuity in velocity potential across the plate. The integral equation is discretized using an expansion-collocation method, involving Chebyshev polynomials of the second kind. A non-trivial solution to the problem is given by the vanishing of the determinant inherent in such a method. Results are given for inclined flat…
