| Abstract: | In this paper, it is assumed that the incident wave is the 2nd-order Stokes wave. The asymptotic expansion and radiation condition of the 2nd-order scattering wave induced by the structure are developed by studying the 2nd -order scattering problem in the far field. It is demonstrated that the energy of the 2nd-order scattering wave is due to the 2nd-order incident wave and the Ist-order fluid field. The outward energy fluxes of the two 2nd-order scatterring waves corresponding to the different sources decay on the different orders. |
