Protective structure

A protective structure (1) comprising:

• a body (2) which is an air and/or space vehicle;
• at least one protective layer (3) made of vanadium oxide (VO2) located on the body (2) and has conductive or insulating properties at a temperature predetermined by a user;
• at least one magnetic layer (4) coated on the protective layer (3) with an impedance value predetermined by the user, wherein when warfare waves (F) directed to the body (2) for an attack is almost equal to the impedance value predetermined by the user, the magnetic layer (4) substantially absorbs the warfare waves (F) and is heated by high resonance frequency, thus increasing a temperature of the protective layer (3) and rendering it a conductive structure, so that the warfare waves (F) are reflected back from the protective layer (3);
• and
• at least one radar absorbing layer (5) located between the body (2) and the protective layer (3), wherein when radar waves (G) are directed at the air and/or space vehicle with an impedance value lower than the impedance value of the magnetic layer (4) predetermined by the user, are at least partially absorbed on the magnetic layer (4) and create a low resonance frequency, the radar absorbing layer (5) allows the protective layer (3) to act as an insulator by remaining under the temperature predetermined by the user, and allows the radar waves (G) passing through the protective layer (3) to be substantially absorbed.
