Abstract :
An explicit expression of PO-EECs (physical-optics equivalent edge currents) based on the concept of modified edge is derived. The magnetic equivalent edge currents according to this concept contain the term excited by the edge component of electric fields of the incident wave, in contrast to other PO-EECs. It is also numerically demonstrated that different PO-EECs give the same diffracted fields in plane wave incidence. This arbitrariness of PO-EECs may exist even if the source is close to the scatterer.<>
