Abstract
Numerical calculations of the thermal emissivity ε of spectrally selective surfaces consisting of absorbing films on reflective metal substrates are reported. A physically realizable form for the absorption coefficient of the film α (ω), and a refractive index n (ω) derived from α (ω) via a Kramers‐Kronig relation were used to obtain new lower limits for ε.Keywords
