Secondary diffraction of a plane wave by a two-part impedance strip

摘要

The scattering of high-frequency waves by two-part impedance strips is an important topic in diffraction theory because it can provide usefull information concerning the radiation of electromagnetic waves in the presence of discontinuity in the material properties of a surface of finite width, as well as of composite structures on aircrafts, satellites etc. According to the Geometrical Theory of Diffraction (GTD) the primary diffracted fields from a two-part impedance strip can be evaluated easily by using the known canonical solutions related both to an impedance half-plane and to a two-part impedance plane.
