This review is essentially based on the results of microwave absorbing materials which are increasing in demand due to their unique absorbing microwave energy and promising applications in the stealth technology of aircraft, television image interference of high-rise buildings, and microwave dark-room and protection. Extensive study has been carried out to develop new microwave absorbing materials with a high magnetic and electric loss. Electromagnetic absorbers are specifically chosen or designed materials that can inhibit the reflection or transmission of electromagnetic radiation. This can be accomplished with materials such as dielectrics combined with metal plates spaced at prescribed intervals or wavelengths. Various parameters such as particular absorption frequencies, thickness, component arrangement and configuration of the materials determine the capabilities and uses of these materials. In this review the effect of single and multilayer types of materials as well as effect of variation in thickness of materials on microwave absorption properties is examined and concluded.
