INTERACTION OF ELECTROMAGNETIC RADIATION WITH CRYSTAL LATTICES

Abstract

The interaction between electromagnetic radiation and crystal lattices is studied, to see how far-infrared radiation is absorbed, transmitted, and reflected by various kinds of crystalline materials. The use of isotopically enriched constituents of crystals for the purpose of identifying effects due to lattice vibrations is described. The studies show that the position of the wavelength for maximum absorption can be understood on the basis of the simple theory, but that the shape and the depth of the absorption curves cannot be predicted in detail by any current theory. The results of the study may eventually be of value in the development of sources and detectors for scientific and technological application, and in the design of optics and detectors for infrared guidance systems.
