角锥型吸波材料应用新探

Application of pyramidal absorbing material

采用碳纤维与磁性微粉复合做成小尺寸角锥型吸波材料 ,具有良好的吸波性能 .角锥设计成高 1.5cm ,底座高 0 .35cm ,尖顶角 4 5° .经测量 ,2 # 材料在 2～ 18GHz频率范围内反射率在 - 10dB以下 ,3.72GHz处峰值反射率达 - 2 0 .

There was good absorption performance in small size pyramidal absorbing material made of carbon fiber and magnetism powder. Carbon fiber was electronic loss material characterized by low density and high intensity. It built up mechanism performance and reduced mass. Magnetism powder was characterized by big permeability and magnetism loss. Pastern can endure high temperature and had stable physical chemistry performance. The pyramid was designed to be 1.5?cm high, its basement was 0.35?cm high, and peak angle was 45°. It was measured that reflectivity for 2 # was below -10?dB in 2～18?GHz and apex reflectivity was -20.86?dB in 3.72?GHz.
