S. Asghar et al., DIFFRACTION OF AN ELECTROMAGNETIC-WAVE FROM AN INFINITELY LONG SLIT IN AN INFINITE METALLIC SHEET, International journal of infrared and millimeter waves, 18(9), 1997, pp. 1821-1836
The diffraction of an E-polarized and an H-polarized wave by an imperf
ectly conducting slit (on which impedance boundary conditions are impo
sed) in an infinite metallic plane is investigated. The two independen
t problems are solved by using integral transforms, the Wiener-Hopf te
chnique and asymptotic approximations. It is found that the diffracted
field consists of the sum of fields produced by the two edges of the
planes formed by the slit and a field due to the interaction of the tw
o edges.
