Abstract: A microwave deicing and anti-icing system for aircraft wings, rotors, and airfoils. Microwave energy is absorbed in a propagation tube inside the leading edge of the aircraft wing and turned into thermal energy. An highly absorptive coating on the interior surface of the tube and a mirror/insulator are used to insure the most efficient transforming of the microwave energy into thermal energy. The thermal energy is then conducted to the skin of the wing, rotor, or airfoil by thermal transfer vanes to the skin of the leading edge of the wing, rotor, or airfoil, so that the temperature in that part of the wing, rotor, or airfoil can be raised and maintained well above the freezing temperature to break and prevent ice.
