Materials' Characterization of Electromagnetic Wave Absorber in Reducing the Electromagnetic Interference Pollution-A Review

The usage of electronic devices in our daily lives is increased to have a better life with many solutions provided by the devices in this modern era where it led to an electromagnetic interference that affect our health. Therefore, many researchers have an interest in synthesizing an electromagnetic interference absorbing material that can provide the maximum benefits to the society. This short review paper will be discussed on different materials can be used to reduce the electromagnetic interference pollution apparently by identifying the materials’ characterization such as the reflection loss, morphological and structural properties. The methods used in preparing the materials also had come into discussions that has become one of the factors affecting the performance of absorbing the electromagnetic interference. Different structure that enhances the properties of absorbing the electromagnetic wave is also highlight in this short review. These different types of morphologies of the materials play an important role in determine the material performance where it could provide mechanisms in absorbing the electromagnetic interference. The doped materials also help the main materials to exhibit their capabilities as an electromagnetic absorbing material.
