Reflecting and transmitting effect of a planar unidirectionally conducting screen

O441; The reflecting and transmitting effects of a planar unidirectionally conducting screen are analyzed based on the accurate closed-form expression for electric field of an arbitrarily oriented electric dipole. For a dipole oriented along the wire elements of the screen, the screen acts as a perfectly electrically conducting plane.For a dipole perpendicular to the wire elements, the fields reflected by the screen can be interpreted as the contribution of an image dipole and image transmission-line current source, while the transmitted field is arisen from image transmission-line source. The expressions of related surface waves are derived and can be compared with previous results.
