In the present world, electromagnetic radiation pollution has become a problematic issue in order to run electronic equipment as well. At this juncture, the necessity of absorbing the electromagnetic radiation emerged as a significant task. Thus, the advanced ceramic materials for microwave absorption property were developed. In the current chapter, the discussion on the effect of electromagnetic radiation on electronic goods, human health and defense system was elaborated. Furthermore, various ceramic materials were introduced for reducing the electromagnetic radiation pollution thereby microwave absorption process. Moreover, in order to evaluate the microwave absorption property of ceramics, we extracted the parameters like magnetic loss and dielectric loss for each ceramic material. Subsequently, the applications of microwave absorbers in various fields were elucidated.

Keywords: Dielectric loss, Magnetic loss, Magneto-ceramics, Microwave absorbers.
