Abstract
The time-scattering of an electromagnetic wave by a wedge-shaped regio n in a lossy medium, both with frequency dependent electric characteri stics, is analyzed for plane wave and line source illuminations. New e xact analytical expressions, satisfying explicitely the causality and allowing useful physical decompositions of the field, are obtained in these cases, using the particularities of the harmonic response in Som merfeld-Maliuzhinets integral, especially original properties of the s pectral function attached to it.
