Abstract

In this paper, an electromagnetic wave absorption component consisting of carbon microcoils is realized. An electromagnetic wave absorber operating in K band and V band is implemented by carbon microcoils which are enwrapped in PDMS. Samples containing carbon fibers and carbon microcoils with different lengths were used as contrasts in the absorption experiment. The measured absorptions of the carbon microcoils are 15 dB (97%) at 26 GHz and 20 dB (99%) at the region from 64 to 70 GHz. The experimental results show that the carbon microcoils are superior in electromagnetic wave absorption and may be considered as a useful tool in future EMI/EMC applications.
