A review of the amount of microwave signal loss of absorbentpolymer nanostructures

One of the most widely used military methods in order to avoid the radar of the surfaces offlying objects that today It is widely used by organizations and defense bodies. The use ofpolymer nano coatings is an absorber of electromagnetic waves, during which a lot of researchhas been done. In this research, the amount of radar signal loss by various types of nanoabsorbent materials such as dielectrics, carbon nanotubes, graphene along with efficientmagnetic poles such as iron carbonyl, ferrites, nano-sized metal oxides, etc., was investigated.It is considered that it performs a significant function in the direction of electromagneticabsorption and transmission and can create a radar signal loss equivalent to -۱۰ dB, which isequal to over ۹۰% absorption, in different frequency ranges.
