Research output: Contribution to journalConference articlepeer-review


The properties of the surface currents induced by a plane wave incident on a plate with multiple apertures are considered. The moment method surface path formulation is incorporated to compute the surface current density for a solid plate, plates with widely-spaced apertures, and plates with closely-spaced apertures. The influences of the aperture separation and incident wave polarization on the currents are also discussed. Surface current maps resolved by the Method of Moments (MoM) are contrasted with surface currents calculated by the Physical Optics (PO) approximation. These comparisons are employed to elucidate the dissimilarity between the MoM and PO predicted by RCS consequences.
