Abstract:It is important in many experiments where electromagnetic radiation is guided by means of mirrors, light pipes or waveguides, to know the reflective properties of the surfaces involved. The authors extend the data available for the reflectivity of copper surfaces for sub-millimetre radiation in the wavelength range 0.2-1 mm (50-10 cm-1). The experimental data are compared with theoretical values based on expressions for the reflectivity of a metal surface derived from electromagnetic theory. It is found that a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
