A non-metal invisible material, belonging to the field of invisible new materials and mainly aimed at solving the problem of "visibility" caused by the reflection of radar waves. The problem is solved since the material has a special function, shown in no reflection or very low reflection probability under radar wave detection, realizing the "invisibility" to the radar wave detection substantially in a way such as electromagnetic wave absorption, attenuation, deflection, blocking and the like. The material, with addition of an auxiliary material, is made into various articles of utility such as a radar invisible coating, invisible clothes, an invisible membrane and the like via corresponding processes, can realize the invisibility to radar centimeter waves, millimeter waves, infrared rays and visible light, and under the radar wave detection, has only a reflectivity (RCS) of less than 0.03-0.003 square meter. Main uses of the material are as follows: in the military, no-reflection invisibility to the radar wave and invisibility to the visible light of offensive and defensive weapons; in civil use, the manufacture of an electromagnetically shielded secret room with no radio wave interference. The material has scope for development in the fields such as scientific research, information safety, electronic countermeasures, counter-terrorism and the like. |
