Measurement and Investigation of Electromagnetic Shielding Properties of 3,4 Ethylenedioxythiophene - Maghnite - Sodium
Conducting polymer composite is an alternative to conventional shielding materials. The present study aims to investigate the electromagnetic shielding characteristics and shielding effectiveness of the sheet of 3,4 ethylenedioxythiophene associated with maghnite and sodium. Waveguide measurements are used to obtain the shielding effectiveness of the studied material. Measurements have been carried out over a 9 GHz to 11 GHz frequency band. Also, dielectric probe measurements are performed to recover the dielectric permittivity of the composite. In addition, the reflection loss, the absorption loss and the shielding effectiveness measured from tests were compared with the values calculated from the transmission line theory.
