This paper presents a review of studies of interference absorbing materials, which come in three basic types: normal interference absorber, Jauman absorber and FSS absorber. And we particularize the structures, applications and methods of analysis and design of each of these types. Results show that the FSS absorber provides a better absorption ability and is more practicable, and that active multi-layer FSS absorber represents a new direction of interference absorbing material research.
