Abstract

Uniform spectral asymptotic descriptions of the scattered fields from general curved surfaces are discussed. Attention is then drawn to scattered fields from surfaces with positive Gaussian curvature, which encompasses the majority of practical reflector geometries. These specific surfaces are modeled by asymptotically approximating the physical optics solution in the spectral domain. A uniform edge correction using the geometrical theory of diffraction is systematically included in the spectral domain, with recovery of the spatial domain field by fast Fourier transform.
