Abstract
The thermal emissivity and related infrared optical properties are calculated for aluminum-backed polyester films in the range -40 to 100C. The aluminum layer is described by the Drude model, or treated as a perfectly-reflecting layer. Effects of multiple reflection and interference are fully included in the theory. Results are presented as a function of the thickness both of the polyester and of the aluminum layer. Calculations of the emitted radiation as a function of frequency and angle show that the apparent emissivity depends very little on viewing angle but is sensitive to the frequency response of the detector.
