Restrictions on the Inversion of the Fresnel Reflectance Equations
The regions for which the Fresnel equations can be inverted to determine the optical constants, n and K, from polarized reflection measurements of a plane electromagnetic wave are presented for different angles of incidence. The sensitivity of the inversion procedure to plus or minus 1% error in the measured reflectances is presented graphically. Such a small error in reflectances could produce a large error, more than 20%, in the determined optical constants n and K with K being the more erroneous. Angles of incidence in the neighborhood of 10 degree and 80 degree produce the largest acceptable regions for inversion.
