In connection with rapidly increasing progress in the radio communication services and other technical branches, which influence electromagnetic environment, the problems connected with electromagnetic compatibility occur. Because of the electromagnetic interference minimization it is necessary to ensure the shielding of sensitive devices, buildings and also persons. The suitable alternative to the classical shielding materials can be special shieldingfabrics.The main advantages of these fabrics are their low weight, flexibility and their easy processability. Shielding is a very popular method of ensuring electromagnetic compatibility and of protecting electronic and electrical equipment and human beings against radiated lectromagnetic energy. The knowledge of shielding efects of diferent types of material represents a basic prerequisite for further development and implementation of shielding devices. This paper presents an analysis of the measuring methods and a comparison of diferent materials in terms of their specific shielding efects. The absorption properties of the various submitted samples were measured using both a Crawford chamber and the Insertion loss method. In the samples, the apacity to absorb electromagnetic waves was determined with the help of a spectral analyzer.
