摘要:
An electromagnetic wave absorber contains cement and carbon nanotubes and has an absolute value of a complex relative permittivity in a range of from 2.0 to 10.0 in a frequency range of from 1 to 110 GHz and a minimum value of a dissipation factor of 0.35 or greater in the frequency range of from 1 to 110 GHz.
