## Two Phase Fresnel Reflectivity and Electric Field Calculation

Brought to you by the
Research Group of
Prof. Robert M. Corn

at the Dept. of Chemistry, University of California, Irvine.

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:

- prism (BK7 or SF10 glass) - air
- prism (BK7 or SF10 glass) - water
- air - metal (gold or silver typically)
- water - metal (gold or silver typically)
- liquid -liquid interface (e.g., CCl4-water)

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.
