摘要
用新型等效源法计算电磁场问题得到的方程一般是满阵且条件数较高,而利用具有高阶消失矩特性的小波化简方程,可以改善方程的性态,提高计算精度,并能节省计算时间。理论分析和实例计算结果表明,将小波分析与新型等效源法结合,是一种非常有效的计算方法。
Wavelet analysis is used to extend the domain ofapplicativn of refined equivalent source method (RESM ). Arefined equivalent source-wavelet mcthod (RESWM ) is thusproposed to reducing the calculating time and inereasing cal-culating precision. Two examplcs of 3-D field caused bymultiple axisrmmetrical electrodes have been calculated byusing the method. The calculated results show that this ap-proaeh gives higher computation aecuracy in comparisonwith the conventional equjvalent source method.
