Paper Abstract

Four references and two arrangements are described for cavity emissivities greater than one. There are different types of emissivities, but all depend on a radiometric output divided by what that output would have been if it had come from an ideal blackbody. Cavity emissivities can be greater than one for a nonisothermal cavity when the temperature of the reference blackbody is selected to have a lower value than the temperature of most of the cavity wall surface.
