Popular techniques to mitigate EMIElectromagnetic Interference (EMI) are explored in this chapter. Conventional metal shielding is one of the most straightforward solutions for EMIElectromagnetic Interference (EMI) mitigation.

On the other hand, microwave absorbersAbsorber designed with polymerPolymer nanocompositesNanocomposites exhibit characteristics such as ease of manufacturing, relatively lower manufacturing costs, low weight, and corrosionCorrosion resistanceResistance. Hence, polymerPolymer compositeComposite-based absorbersAbsorber are investigated in this chapter. The design characteristics of microwave-absorbing materials are also explored.
