Efficiency of Microwave Shielding Composites
2022 IEEE 41st International Conference on Electronics and Nanotechnology (ELNANO)(2022)
摘要
High frequency electromagnetic pollution in the environment needs strong attenuation of unwanted noise as for protection of electronic devices interference so for human health. Effective defense from the electromagnetic chaos can be realized by the layer of flexible absorbing microwave composite based on the polymers filled with conductive, magnetic or dielectric powder absorbers. General electromagnetic analysis is given both for the protective absorbing shielding so for absorbing materials selection. As determined, the absorption capacity of conductive and magnetic fillers decreases with increasing frequency, while fillers made of high-loss dielectric increase their absorbance with frequency rise. Substantiations are given for obtaining optimal electromagnetic parameters for shielding composites.
