摘要：

A new method for determination of the dielectric function-epsilon is presented. The experiment is based on the simultaneous measurement of the Brewster angle-phi(B) and the reflectivity R(p) for light polarized parallel to the plane of incidence. epsilon-1 and epsilon-2 as a function-phi(B) and R(p) were calculated and the results plotted as contour plots with the optical constants as parameters. Spectral measurements yield epsilon-1 and epsilon-2 as a function of photon energy. Results obtained on GaAs are evaluated and correspond well to literature data.
