摘　　要：根据电磁波吸收理论,基于电阻网膜设计制备了一种宽频吸波天花板.实验表明,采用厚度为1.2 cm厚的石膏板,格子型电阻网膜（3格）,电阻条线宽为24mm,在S带（2～4 GHz）,-10 dB以下吸收带宽达到92％,在3 GHz附近有最大吸量-17 dB;随着入射角度的增大,吸收峰逐渐向低频方向移动,带宽逐渐增大.新材料可用于建筑室内电磁污染控制.This article is based on the theory of electromagnetic wave absorption,successfully prepared a wide-band latticetype absorbing ceiling. Test indicates that the absorber composite with thickness of 1.2 cm gypsum board and the line width of the Lattice-type resistance stripe of 24 mm has an absorbing rate band width below -10 dB in S-band （2-4 GHz） reached 92% and the absorption peak reached -17 dB close to 3 GHz, and the absorbing peak moves to the low frequency and the band-width increases with the incidence angle increasing. The new material can be used for construction interior electromagnetic pollution protection.
