  radiation problems
It is thus concluded that scattering problems can be transformed into specific radiation problems where the radiated source of known distribution is located at infinity.
      
A frequency extrapolation technique for computing antenna-platform radiation problems
      
A frequency extrapolation technique is proposed to obtain the broad band radiation patterns of antenna-platform radiation problems.
      
The algorithm is applied to several 2D and 3D antenna-platform radiation problems.
      
By applying the radiation-to-scattering transform, the scattering problem can be considered as the specific radiation problems where the radiated source equivalent to the electromagnetic plane wave is located at infinity.

This paper extends the simple Green's function technique to calculatesecond-order potentials and forces for two-dimensional rediation problemsat finite water depth.Based on first-order solution,the second-order potential in outer region can be described analytically,which gives accurate condition for the radiation boundary.The conditions on other boundaries ofinner region are calculated by numerical differentiations of the first-orderpotential.Similar to first-order problem the second-order potential isobtained by use of Green's theorem for inner region taking simplefunction lnr to be Green's function.The computer program developed has produced results for a semi-circle oscillating on the free surface of deep and shallow water domains.

本文将简单 Green 函数法推广到有限水深二维辐射问题的二阶速度势和水动力计算。在求得一阶势以后,可以写出二阶势在外部域中的解析形式,从而准确给出二阶势的辐射面条件。二阶势在内部域其它周界上的边界条件则由一阶势的数值微分求得。象求解一阶势一样,仍用简单函数 lnr 作为 Green 函数,对内部域利用 Green 公式求解二阶势。本文给出半圆在深水和浅水两种不同水域表面振荡时的二阶势和二阶力计算结果。

A computational model is presented for calculation of the nonlinear radiation problem of an arbitrary body in time domain. The semi-Lagrangian method has been used to simulate fully three-dimensional nonlinear free surface. A special treatment of the free surface and body intersection points is used, which avoids the difficulties associated with the singularity at the intersection points. The main topics in this paper are,(1) The effects of different typies of radiation conditions to the nonlinear radiation solution;(2) The effects of changing distances of the open boundary surface to the radiation solution under Orlanski's open boundary condition;(3) The effects of changing amplitudes of body oscillations to the radiation solution.We have also used our computation program to calculate the examples given by Lin at al. The numerical results show good agreement with Lin' s method of matching the finite computational domain to a linear outer solution.

Numerical calculation of fluid-structure acoustic coupling vibration were carried out for a 3-D elastic structure with FEM applied to structure analysis and BEM to fluid respectively. An emphasis is laid on the calculation of matrix elements in BEM. The combination problem at the fluid-structure boundary is solved and calculation is simplified. Numerical results of a practical example prove that the calculation method is satisfactory.
