| 摘 要： | 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。

| Abstract: | The asymptotic waveform evaluation(AWE) technique in conjunction with the Pade estimation approach is applied to predict the surface current of two dimensional(2D) perfect electric conducting(PEC) cylinder.The field component at any given point on the surface is solved by using the on-surface discretized boundary equation(OS-DBE) method,the AWE technique can sweep the source distribution in the spatial domain,exact extension of the point through AWE is determined by Pade estimation approach.According to abo... |
