Abstract : Various quasi-optical components for effective beam transmission at near millimeter wavelengths have been studied. A double-beam apparatus which may be configured as a Mach-Zehnder interferometer has been assembled for dielectric characterization of materials. Values of optical constants, obtained at a frequency of 245 GHz with an optically pumped laser source, are reported for several low-loss materials. The potential for improvements and increased accuracies are discussed. (Author)
