Infrared Cloaking, Stealth, and the Second Law of Thermodynamics [PDF]
Entropy, 2012 Infrared signature management (IRSM) has been a primary aeronautical concern for over 50 years. Most strategies and technologies are limited by the second law of thermodynamics. In this article, IRSM is considered in light of theoretical developments over the last 15 years that have put the absolute status of the second law into doubt and that might ...
