Electromagnetic radiation shielding properties of copper containing activated carbon
Abstract
It's proposed to modify the consist and electromagnetic radiation shielding properties of powdery activated carbon by the method of chemical deposition of copper clusters on the surface of fractions of such material. The choice of these element caused by it resistance to the environment conditions, which could determines the stability of the shielding properties of materials including of these elements. Regularities of electromagnetic radiation interaction with powdery activated carbon modified by the proposed method were researched. According to the results of this research it's established that electromagnetic radiation reflection coefficient in frequency range 8…12 GHz of shields made with powdery activated carbon decreases from –2 to –14 dB after modification of such material consist.
