Hybrid Polymer Composites For Electromagnetic Absorption In Electronic Industry

Abstract

The objective of this chapter is to provide an overview of the use of hybrid polymer composites in the field of electromagnetic compatibility. The principles and theory of electromagnetic shielding are reviewed, and the respective fundamental quantities are defined. With a view to the actual applications, the materials requirements for the noise suppression sheets and electromagnetic wave absorbers are discussed. Thereby, the critical issues of reliable material properties characterization and electromagnetic performance evaluation are considered. Particularly, expressions of reflection bandwidth are developed and proposed as appropriate figures-of-merit for absorbing materials. Finally, by reviewing the studied multicomponent filler systems, the different approaches in composites design to achieve suppression of reflectance or transmittance are presented.
