The Research Progress of Wave-Absorbing Materials

Due to the increasing use of GHz electromagnetic waves in military,industrial and commercial applications,the electromagnetic wave interference（EMI）has become a new pollution.The electromagnetic radiation disturbes other electronic facilities,and also deteriorates the health of human being.So,the electromagnetic wave absorption materials have been widely studied and applied.With the development of the stealthy and anti-stealthy,the demand of vacuum devices for high-Power,the widespread popularity of electronic communication,and the electromagnetic pollution increasing,the development of micro-wave absorbing material has been the one of the hot spots in functional materials.It was summarized the physical mechanism of wave-adsorbing materials,the wave-adsorbing quality,the classifications of wave-adsorbing materials and the application fields of wave-adsorbing materials in this article.Finally,it was indicated that the multi-crystal metallic fiber、SiC-based ceramics and C/C composite materials was a optimum properties and a first-rate applied prospects wave-adsorbing materials in the present.
