The diffraction of an inhomogeneous plane wave by an impedance wedge in a lossy medium

The diffraction of an inhomogeneous plane wave by an impedance wedge embedd ed in a lossy medium is analyzed. The rigorous integral representation for the field is asymptotically evaluated in the context of the uniform geometr ical theory of diffraction (UTD) so that the asymptotic expressions obtaine d can be employed in a rag analysis of the scattering from more complex edg e geometries located in a dissipative medium Surface wave excitations at th e edge and their propagation along the wedge faces are discussed with parti cular emphasis on the effects of losses.
