Effect of polarization on spacecraft radiation heat transfer
The fact that polarization affects radiation heat transfer is pointed out and illustrated with calculations for the interreflection of solar energy among spacecraft components. The general case of radiation transfer in an enclosure with account taken of polarization is formulated, and special cases are set up in detail for engineering calculations. These special cases are specular reflection from isotropic and anisotropic solids and one reflection of solar energy from an imperfectly diffuse solid. Qualitative rules are given to guide the engineer in deciding whether or not polarization should be considered.
