【 摘 要 】

The absorbing properties of activated carbon were studied and tested by making use of RCS in "the reflectivity testing measurement of radar absorbing material" of GJB 2038-94 in this work. The effect of electromagnetic parameters and thinness on absorbing properties of materials was discussed. The results indicate that in the whole 12∼18 GHz frequency band, the dielectric constant decreases with increasing frequency, the dielectric loss angle tangent with the frequency gradually increased, and the activated carbon is a kind of anti magnetic media, but it also has some paramagnetic. The sample thickness has little effect on the wave absorbing property in the 12∼18GHz frequency band;
