Abstract
Highly adherent and homogeneous polypyrrole thin films were deposited on copper from sodium oxalate solution for different molar concentration. The electromagnetic reflection, absorption, permittivity and conductivity studied in the frequency range 8- 12 GHz is reported. Polypyrrole increases the reflection of copper but decreases the microwave absorption. The absorption is highly dopant concentration dependent. As dopant concentration increases the permittivity and microwave conductivity increases.
