J. G. Collins [Appl. Sci. Res. Sec. B7, 1 (1958)] and K. L. Kliewer and R. Fuchs [Phys. Rev. 172, 607 (1968)] have shown that, in principle, two dielectric functions are needed to represent the optical behavior of a solid, one for describing p polarization and another for s polarization. The variation of the polarization of the output from a grating monochromator with wavelength and with grating coating has been demonstrated by K. Rabinovitch, L. R. Canfield, and R. P. Madden, Appl. Opt. 4, 1005 (1965).
T. T. Cole and F. Oppenheimer [Appl. Opt. 1, 709 (1962)] report values of n and k for Al between 10.2 and 40.8 eV although, as they remark, their specimen-preparation conditions were not rigorous enough for their values to represent the properties of pure, bulk Al.

F. Sauter [Z. Physik 203, 488 (1967)] and F. Forstmann [Z. Physik 203, 495 (1967)] have shown that the usual Fresnel equations do not give correct values of the reflectance in the vicinity of the plasma frequency. The correction, however, is 1% or less in the case of Na and this correction is insignificant compared to the usual measurement accuracy.

R. H. Ritchie [Surface Sci. 3, 497 (1965)] has suggested that optical absorption due to surface plasmon excitation can occur. This prediction has been confirmed by three groups who find that silver samples show variable absorption near the surface plasmon energy of 3.6 eV that can be correlated with surface roughness [J. L. Stanford, H. E. Bennett, J. M. Bennett, E. J. Ashley, and E. T. Arakawa, Bull. Am. Phys. Soc. 13, 989 (1968); S. E. Schnatterly 13, 989 (1968); P. Dobberstein, A. Hampe, and G. Sauerbrey, Phys.
