Abstract

Measurements of the Optical Constants of Metals at Submillimeter Wavelengths Are Sparse. We Have Used a Nonresonant Cavity to Measure, at Room Temperature, the Angle Averaged Absorptance Spectra P(W) of Aluminum, Molybdenum, Tantalum, Titanium, Tungsten, and Iron in the 30-300-Formula Presented Wavenumber Region.The Real Part of the Normalized Surface Impedance Spectrum, Formula Presented, Was Determined from Formula Presented.Measurements Were Also Made on Iron from 400 to 4000 Cm 1 using Standard Reflectance Techniques. the R(W)spectrum Wascombined with Previous Measurements by Others at Higher Frequencies and Kramers-Kronig Analyses of the Resultant Combined R(W) Spectra Provided Formula Presented. © 1988 Optical Society of America.
