Based on the ellipsometry method proposed, the optical anisotropy of the porous material was investigated. The anisotropy was assumed to be uniaxial with the optic axis normal to the sample surface. Results show that the anisotropy in the EMA2 was found to be small and the difference in porosity between ordinary and extraordinary directions was less than 3%. Thus, neglecting anisotropy does not significantly affect the outcome of the results and discussions presented.
