Abstract
The field scattered by a scattering body or by an aperture in the free space (or in an unbounded homogenous medium) can be described in terms of a double integral. In this paper we present a new asymptotic uniform evaluation for this kind of integrals that is expressed in the format of the uniform geometrical theory of diffraction (UTD), which is convenient for numerical computations.
