摘　　要：将等效原理和分离变量法结合，提出了求解电磁场的新型等效源法。该方法的通解形式为无穷级数。在该方法中有确定等效源位置的具体方法和原则，这些方法和原则完全适用于模拟电荷法及广义多级技术，并使它们从经验的约束中解脱出来。从与模拟电荷法对闭合场域计算结果的比较中可明显看出新型等效源具有许多优点。Combining theorem of equivalency with separation of variable, a new equivalent source method(NESM), the general solution to which is infinite series, is proposed in this pa- per. The approaches and principle suggested in NESM to determine the location of the equi- valent source are entirely adapted to the generalized multipole technique(GMT) and the charge simulation method(CSM) and contribute to extricating them from the bounds of experience. Compared with the result of calculating bounded field by means of CMS, NESM has many obvious advantages.
