IR radiometer sensitivity and accuracy improvement by eliminating spurious radiation for emissivity measurements on highly specular samples in the 2 to 25 μm spectral range
Telmo Echániz, Raúl Benjamín Pérez-Sáez, Manuel José Tello
This paper indicates that the sensitivity and accuracy of an infrared radiometer for emissivity measurements depends not only on its design and the measurement method, but also on…

Experimental verification of the anomalous skin effect in copper using emissivity measurements
Telmo Echániz, Iñigo Setién-Fernández, Raúl Benjamín Pérez-Sáez +1
Spectral directional emissivity has been measured in copper between 3 and 24 μm above room temperature. The experimental spectrum shows a weak broad peak between 7 and 14 μm, which…
