Abstract :
The Modified Edge Representation is an approximation method in surface-to-line integral reduction from Physical Optics to calculate the field of diffraction. The accuracy is good in most of cases but the errors become notable near reflection shadow boundary only if the scatterer is convex with big curvature. This paper focus on the correction with higher order of PO-MER EECs for enhancing the accuracy in this specific condition.
