| Abstract(in English) | We aimed improvement of the performance of electromagnetic wave absorption and noise suppression for near field and far field we evaluated and analyzed electromagnetic wave absorption performance of the sheet materials based on paper with Carbon nanotubes. The sheets were coated by Carbon nanotubes paste. The measurement method was reflection (S11) and transmission (S21) using a coaxial tube , and relative permittivity was measured by the NIST Precision. As for the near-field, Rtp was evaluated from the S11 and S21 measurements by the microstrip line. As a result, the electromagnetic wave absorption performance reached 20dB in the frequency band from 10 GHz to 20 GHz, indicated that is validity to effective for noise suppression. |
