渐近波形估计(AWE)技术结合帕德(Pade)逼近的误差估计方法可以快速预测二维理想导电柱体的表面电流。首先采用表面离散化边界方程(OS-DBE)法对导体表面任意点的未知场源进行求解,其次运用AWE技术获得该点附近一段区域的场源分布,然后通过帕德逼近的误差估计方法可以确定AWE展开的确切范围。依此步骤进行下一个点的计算,最终可以求得导体表面上全部点的场源分布。计算结果表明此方法很大程度上提高了OS-DBE法的计算效率和AWE技术的实用价值。
Asymptotic waveform estimation (AWE) and Pade approximation error estimation method can quickly predict the surface current of two-dimensional ideal conductive cylinder. First of all, the surface field discretization boundary equation (OS-DBE) method is used to solve the unknown field source at any point on the conductor surface. Secondly, the AWE technique is used to obtain the field source distribution in a region near the point. Then, Determine the exact range of AWE expansion. Follow this procedure to calculate the next point, and finally you can find the field source distribution of all the points on the conductor surface. The calculation results show that this method greatly improves the computational efficiency of OS-DBE method and the practical value of AWE technology.
