Electromagnetic characterisation of Pani/PU in multi-layered structure, application for EMI protection at microwave frequency

Nowadays, the electromagnetic interference problem becomes more important to protect the electric, electronic devices. In this paper, the electromagnetic characterisation of Pani/PU in multi-layered structure was studied in order to optimize the shielding effectiveness at the microwave frequency. In the three-layered structure, the insulating layer increases not only the mechanical properties but also improve the shielding effectiveness.
