Abstract :
The electric field diffracted by a strip caused by an incident cylindrical wave with E parallel to the edge, at various angles of incidence, is measured in a parallel plane medium. The field is compared with that computed from geometrical optics currents and with the addition of equivalent line currents at the edges. The edge "line currents" improve the geometrical optics current field particularly at oblique incidence.
