Ht. Ha et Jw. Ra, EDGE-DIFFRACTION BY AN ARBITRARY-ANGLED WEDGE COMPOSED OF METAL AND LOSSLESS DIELECTRIC, Microwave and optical technology letters, 16(2), 1997, pp. 89-93
A rigorous formulation is suggested for solving the scattering of plan
e waves by a composite wedge of metal and lossless dielectric. This em
ploys the Kirchhoff integral in the physical regions and the extinctio
n theorem in their mathematical complementary regions to make the corr
ection of the primary approximated solutions. Calculated total field p
atterns scattered by the composite wedge give close results to the rig
orous asymptotic field for the limits of the dielectric wedge becoming
conducting or background free space. (C) 1997 John Wiley & Sons, Inc.
