Abstract：Based on space electromagnetic wave propagation principle,a design idea that multi-layer hole structural microwave absorbing materials which is based on the present study of EPS cement-based microwave absorbing material is given to solve the existing problems with cement-based microwave absorbing materials (CMAM);To study the influence of EPS content and resistive film value of resistance on CMAM's microwave absorbing property,small particles of EPS,resistive film which is made from graphite and carbon black were prepared for study.After designing different number,location and size of the hole,a multi-layer holed structural microwave absorbing materials with better microwave absorbing properties (the minimum reflectivity near 4 GHz is -18.5 dB),wide frequency bandwidth (reflectivity less than-10dB reaches 15.5 GHz of bandwidth) was prepared by using 20 mmthick sample between 2 to 18 GHz frequency band.
