摘要 文章给出了一种改进的等效电磁流公式,该公式是在A.Micheali的表达式的基础上得出的。当观察方向位于Keller锥上时,改进的D_e,D_m表示式可化简为Kouyoumjian ̄[1]的绕射系数,等效电磁流的表达式同Knott和Senior ̄[2]的表达式完全一样。在阴影和反射边界上,改进的等效电磁流表达式具有一致性。 An Improved Version of EquiValent Edge Currents is presented,The expressions of therm proved Equivalent Edge Currents are based on that of A,Michcali’s and finite and shadowand reflection boundaries.
