The Mixed BoundaryValue Problem of Helmholtz Equation in a QuarterPlane[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2011,50(5):7-10.DOI:
The mixed boundaryvalue problem of Helmholtz equation in a quarterplane is studied by means of a new type transform method introduced by Fokas. The integral representation of the solution in closed form is obtained. The results have conveniences both in asymptotic analysis and numerical calculation.
