Derivation of Kirchhoff diffraction integrals for soft and hard surfaces of perfectly electric conductor half-planes
Abstract
In this study, by applying the Kirchhoff diffraction integral to the problem of the soft and hard-surface half-planes, two different diffraction integrals are obtained. To obtain the diffracted fields by the soft and hard-surface half planes the edge point method is used. For the uniform field intensities, Signum function and Fresnel function are used. In the comparison of the obtained diffracted fields, the results are interpreted by means of the plots as well. Similarities and differences between the obtained diffracted fields are discussed for some parameters. It is concluded that in some regions diffracted wave by a soft surface has an intensity higher than the diffracted field intensity corresponding to the hard surface. In some regions, it is vice versa. At the critical points that are related to the incident angle, they have the same value.
