对于任意的局部楔形角和任意的照明和观测方向，导出了等效边缘电流的显式表达式。从而使等效电流法成为一种实用的电磁高频边缘绕射理论。推导基于物理绕射理论(PTD)的表面辐射积分和MEC的线辐射积分之间的渐近关系，所得到的表达式是从正则楔形问题的精确解推导出来的。
Explicit expressions for equivalent edge currents are derived for an arbitrary local wedge angle and arbitrary directions of illumination and observation. Thereby the method of equivalent currents (MEC) is completed as a practically applicable theory of the electromagnetic high-frequency diffraction by edges. The derivation is based on an asymptotic relationship between the surface radiation integral of the physical theory of diffraction (PTD) and the line radiation integral of MEC, and the resulting expressions are deduced from the exact solutions of the canonical wedge problem.
