Asymptotic solution for the diffraction of an electromagnetic plane wave by a cylindertipped halfplane
Abstract
The farfield asymptotic solution for the diffraction of an electromagnetic plane wave by a cylindertipped halfplane is derived from the exact solution. It is demonstrated that the Fresnel diffraction plays an important role in the transition regions where the solution of the geometrical theory of diffraction fails. The asymptotic solution not only simplifies the numerical calculations but also gives a physical model of the exact solution.
