| 摘 要： | 采用涂覆法制备了FeCrAl金属网栅吸波材料.研究了FeCrAl丝的不同丝长度、不同丝间距排布对2～18GHz范围内吸波性能的影响规律.研究表明,连续FeCrAl丝网栅材料不具备吸波性能;随FeCrAl丝长度的减小,材料最大吸收峰向高频方向移动,且最大吸收峰绝对值也随丝长度的减小而增大;随FeCrAl丝间距的减小,最大吸收峰向低频方向移动,且最大吸收峰绝对值也随丝间距的减小而增大.

| Abstract: | Microwave absorbing materials in form of net structure were prepared with FeCrAl filaments and slurry of LAS glass powder,organosilicane resin by manual brush.The effects of filaments length and filaments spa-cing on absorbing properties of the materials in 2~18GHz frequency range were studied.The results show that no absorption was found in the material with continuous FeCrAl filaments net.The absorbing peaks move to the high-frequency with the filaments length decreasing and the absolute value of the peak increases at the same time;the maximum absorption peaks move to the low-frequency with the wire spacing decreasing meanwhile the absolute value of the peak increases. |
