In X-ray or neutron small-angle scattering (SAS), Porod's law, discovered by Günther Porod, describes the asymptote of the scattering intensity I (q) for large scattering wavenumbers q.

Porod's Law: Next consider a sharp smooth surface of a particle such as a sphere. The surface can be decomposed into spherical scattering elements that bisect the particle/matrix interface.

Thus, by extracting the Porod Constant from experimental data, and knowing the contrast factor between the two phases, one can obtain the specific surface area for the material.

This work presents a novel method for the analysis of small-angle scattering data from a highly aligned domain structure based on a modification of the well known Porod law.

The Porod law states that i (h), the intensity of X-radiation scattered by an ideal multiphase noncrystalline system, for `large' momentum transfer values (≡ h) approaches lh−4 and that l is …
