[0002] Aircraft icing is one of the main hidden dangers leading to flight safety accidents; during flight, icing on the surface of the wing leading edge and other components not only increases the weight of the aircraft, but also destroys the aerodynamic shape of the aircraft surface, changes the flow field around the aircraft, and makes the The maximum lift-to-drag ratio of the aircraft decreases, and the stall angle of attack decreases, which affects the maneuverability and stability of the aircraft, and even causes safety accidents in serious cases; the existing methods of anti-icing for aircraft include expansion tube de-icing, ordinary electric anti-icing, gas heating Anti-icing and anti-icing liquid anti-icing, etc., the above-mentioned methods will bring new problems such as affecting the aerodynamic shape, huge energy consumption and polluting the environment; with the continuous advancement of information technology, aircraft stealth technology has attracted more and more attention. Performance mainly depends on shape design and absorbing materials, and some absorbing materials can convert electromagnetic radiation into heat after absorbing it

[0003] The inventors of the present disclosure found that in the existing aircraft anti-icing technology, 1. The characteristics of absorbing materials that can convert electromagnetic waves into heat are not well utilized for anti-icing; 2. Although there are wave-absorbing loads installed on the wings The method of deicing is specifically: a wedge-shaped wave-absorbing material is installed in the wave-absorbing load, and the microwave input into the waveguide load cavity can be matched and absorbed, and the microwave energy is converted into heat energy. However, the above method requires a separate setting of the absorbing material. wave load, the direct use of wave-absorbing materials on the aircraft has not been realized, and the control of deicing operations according to actual conditions has not been realized, and the utilization rate of microwaves into heat energy is low
