摘要：

An alternative formulation is presented for the derivation of the results in [1] 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 >> lambda. This was heuristically conjectured by Franceschetti, et al. (IEEE Trans. Antennas Propag., vol. 56, no. 2, pp. 437449, 2008) and supported by numerical examples, but without a rigorous proof.
