Electromagnetic response of metamaterials is not only determined by its component materials but also the microstructure and arrangements of its resonant elements. The perfect absorber prepared by metamaterial (PMA) can realize 100% absorption in specific frequency bands by designing reasonable structures of resonators. PMA can be applied in many domains, such as stealth material, frequency selective surface, terahertz imaging, micro antenna, intelligent communication, detection and regulation of electromagnetic wave because of its flexible designing, adjustable response, strong absorption, broad band, thin thickness, light mass. Based on the present study situation at home and abroad, we summarized the development, structure, preparation and test of PMA. In order to gain a more profound and comprehensive understanding on PMA, we also explored its trends, prospects and urgent problems. Proactive and intelligent PMA with multi functions and new PMA prepared by new material and new process are the future development trends.
