ADVANCES IN FERRITE MATERIALS FOR ELECTROMAGNETIC INTERFERENCE SHIELDING RESPONSE

In today’s world, electromagnetic interference (EMI) is a modern kind of environmental pollution. With the growing technology, the excessive usage of electronic devices making it more dangerous. EMI not only degrade the working performance of electronic gadgets, but also harmful for living creatures also. There is lots of work present on the significant EMI materials in broad bandwidth frequency like X-band and Kuband. Among them, ferrites are the advanced materials for many applications including the EMI shielding with exceptional magnetic, dielectric, optical and mechanical properties. Various nanocomposites of ferrites with different materials like conducting polymers, carbon materials or metallic particles etc. represent a different class of promising shielding materials. The present chapter exploring the EMI theory and shielding materials related to ferrites
