Abstract
The mixed boundaryvalue problem arising in the study of scattering of twodimensional timeharmonic surfacewater waves by a discontinuity on the surface boundary conditions, separating the clean surface and an icecovered surface, is solved completely in the case of an infinite depth of water. The main problem is reduced to that of solving a singular integral equation, of the Carleman type, over a semifinite range and the explicit solution of the original problem is determined. Neat and computable expressions are derived for the two most important quantities, known as the reflection and transmission coefficients, occurring in such scattering problems and tables of numerical values of these quantities are presented for specific choices of a parameter modelling the ice cover. The absolute values of the reflection and transmission coefficients are presented graphically. The present method of solution of the boundaryvalue problem produces simple expressions far the principal unknowns of the problem at hand and thus provides an easily understandable alternative to the rather complicated WienerHopf method used previously.
