A Uniform Asymptotic Result for the Scattering of Plane Waves by a Circular Cylinder.

Abstract

The canonical problem of plane wave scattering by a perfectly-conducting circular cylinder is analyzed, and a uniform asymptotic result is presented for the field within the transition regions adjacent to the shadow boundaries where the ordinary ray solutions fail. This result provides a finite and continuous total field across the shadow boundaries. Exterior to the transition regions it reduces to the GTD solution in terms of the surface diffracted and the geometric optical (incident and reflected) ray fields for the shadow and lit zones, respectively. The accuracy of this transition solution is confirmed by numerical comparison with the results obtained via an exact solution for the same canonical problem.
