Abstract:Abstract: The absorbing properties of the aluminum foams coated absorbing paint were studied and tested by Radar Cross Section (RCS) method. The influence of electromagnetic wave frequency and absorbing paint species on absorbing properties of materials was discussed. The results indicate that the absorbing properties increase with increasing frequency. The absorbing properties of the materials coated magnetic dielectric absorbing paint are better than others, and that of the sample CFe is the best in the frequency range of 12.0−18.0 GHz, while that of the sample CNi′ is optimal in 26.5−40.0 GHz
