| The diffraction gratings, fabricated in our laboratory, were presented and analyzed by atomic force microscopy in earlier publications. In this paper we apply the Fourier-Pade approximation on our data previously analyzed by fast Fourier transform, proving advantages of using the Fourier-Pade approximation for spectral analysis of structural properties of some optical materials. |
