many thanks for you, DuDu, your suggestion about ' adding a phi(0) ' does make sense, and it matched with one of the references, but that phi(0) is '-pi+abs(delta)', and the 'delta' is depending on the material which is measured, and it is unknow to me. So, if follow your suggestion, i should...

Recent days, i have found some references about the phase extraction as so far, some important steps may include: (i) spectrum extrapolation (equivalent to delta_Phi approximation); (Ref. 1) (ii) the phase 'Phi' should add with a ' phi(0) ', which has the value ' -pi+abs(delta) for...

complex refractive index always in the form n^=n+i*k, for the real part n is the refractive index, imaginery part k is known as absorptive index (absoption coefficient alpha=4*pi*k/lambda). how to say the calculated k has a dispersive shape and n an absorptive one? the measured material is...

the formula has no problem, it can be found in many reference...

I try to extract optical constants (complex refractive index) from the spetral reflectance data - R(omiga), the common method is using Kramers-Kronig relations to calculate the Phase information of the reflection - Psi(omiga), then according to the normal reflection coefficients, the complex...
