Since each factor ˜E(k′) (spatial Fourier transform) is confined to a shell of width∼1/ℓ s centered at|k ′|=k, their convolution should only be appreciable in the|q|≲∆k region

Intensity as convolution As an example, we consider intensity of a scalar fieldE(r) found in a specific realization of disorder (no ensemble averaging) I(r) =E(r)E ∗(r)
