Abstract

This letter proposes the use of carbon black film in absorbing high-frequency power. This low-cost material can be obtained easily using a low-cost fabrication process (i.e., screen printer). The 70 wt% carbon black film is 0.055-mm thick, with sheet resistance of 162-Ω /sq and conductivity of 113.6 S/m. Results show that carbon black film absorbs high-frequency signal, and the power loss reaches 70% at 3 GHz. Moreover, the starting suppression frequency could be controlled by adjusting the proportion of carbon black.
