EFFICIENT PROCEDURE FOR CALCULATING OPTICAL PROPERTIES FROM REFLECTIVITY DATA

Author Institution: Physics Department, The University of Connecticut,A technique modifying the classical Kramers-Kroning procedure, for recovering extinction information from reflectivity measurements, is being advanced. The method utilizes the Fast Fourier procedure instead of the usual Hilbert transform. In this way the calculation can be reduced to only $Nlog_{2} N$ complex add-multiply operations. The comparable results on both model data and real data will be presented
