【Abstract】 Magnetic and conductive light material/epoxy resin microwave absorbing coating are prepared. The electromagnetic parameters and the normal reflectance were measured by using 3cm waveguide method at 9.2?GHz. The results showed that the concentration of magnetic and conductive light material in the coating affected the properties of the coating very much. The optimal concentration of light material in the coating was about 50?%. In this concentration, the coating with 1.7?mm thickness showed good wave absorption with 34?dB peak value and having about 11?GHz wide frequency band reducing about 10?dB.更多还原
