This page is for calculating the reflectivity of p-polarized and s-polarized light (RefP and RefS) as well as the square of the interfacial electric fields (Es2, Ex2, Ez2) as a function of incident angle (Angle) from a two phase dielectric system. The first phase must be non-absorbing (real refractive index only). The second phase can have both a real and imaginary part. Some typical calculations are:
For this calculation, you need to supply the angle range over which you wish to perform the calculation and the indices of refraction for the 2 phases. As mentioned above, the first phase can only have a real index of refraction.
If you don't know the indices of refraction, we have created tables of gold, BK-7, and SF-10, indices of refraction for wavelengths between 500 nm and 2000 nm. The default indices in the form are for air and gold at the HeNe laser wavelength of 632.8 nm.
This particular web page is written to perform only a 2 phase calculation. We also have a web page for a 4 phase Fresnel calculation that uses the N-phase method published in the article by Wilford Hansen, J. Opt. Soc. Am. 1968, 58, 380-390. For more information or a copy of the complete N-phase calculation code, please see our Calculations Page.
To run this calculation, just fill out the form items below and hit the "Submit Parameters" button. Your input data will then be saved, and the calculated Angle-Ref data will be returned in an x-y table.
Good Luck! If you run into any problems, please email us at: email@example.com
