Conducting polymers has a unique property that makes it a good candidate for applications like electromagnetic interference shielding, satellite communication links, beam steering radars, frequency selective surface, and Radar absorbing materials. Conducting polymers with high conductivity can be used as radiating elements of antennas. for more details can pass through the following reference;
Article Conducting polymers for microwave applications
The materials having a high conductivity and dielectric constant will contribute more to high Electromagnetic Interference (EMI) shielding efficiency/microwave absorption. Conducting polymers have high conductivity and dielectric constant for which they can storage and release charge through redox process. The attached paper may help to understand more..............
