Measuring Microwave Emissivities
Abstract
Dicke radiometer and cryoload combined in emissivity determinations of mesh antennas. Newly developed measuring apparatus and procedure fills technological void in accurate determination of surface emissivities at microwave frequencies. Capable of measuring independently electromagnetic emissivity and/or intrinsic losses of surfaces, comprises radiometer, horn antenna, test section, and cryogenically cooled matched load.
