Abstract
An alternative formulation is presented for the derivation of the results in which allows to rigorously extend the validity range to any incidence/observation aspect provided that the standard deviation of the edge roughness sigma is not large compared to the wavelength lambda while the observation distance r is r Gt lambda . This was heuristically conjectured by Franceschetti, (IEEE Trans. Antennas Propag., vol. 56, no. 2, pp. 437-449, 2008) and supported by numerical examples, but without a rigorous proof.
