摘要
基于分域解的思想,扩大了新型等效源法的解题范围,另外在分域时,必须避免物理奇点出现在区域的角点上,以提高计算精度.由于新型等效源法能确定等效源的位置和个数,产生的场量值可用级数表示,所以模拟效果较原有等效源法好得多.实例计算结果表明,该方法在很大程度上能提高计算精度,而且未知数也减少了许多.
The concept of subregion is used to extend the domain of application. A refined equivalent source method (RESM) is thus proposed reducing the errors of the boundary corners. Since the position and number of the equivalent source can be determined theoretically and the field distribution can be expressed in series form, computation accuracy is gained in comparison with the conventional equivalent source method.
