Abstract
The extension of the geometrical theory of diffraction (GTD) to complex ray s is considered. The key difference with real rays arises in the determinat ion of the regions of existence of the incident and reflected fields, which are governed by Stokes phenomenon. The procedure is demonstrated using the simple example of diffraction by a finite plate. (C) 2001 Elsevier Science B.V. All rights reserved.
