摘    要:

采用雷达截面法研究表面涂覆吸波涂料的泡沫铝复合材料的吸波性能,讨论电磁波频率和吸波涂料种类对材料吸波性能的影响。结果表明,材料的吸波性能随频率的增加而增加;表面涂覆磁介质型吸波涂料的泡沫铝复合材料的吸波性能较佳,在12.0~18.0 GHz频段内样品CFe的吸波性能最好,而在26.5~40.0 GHz频段内样品CNi′的吸波性能最好。

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
