Research Progress in Theoretical Designs of Microwave Absorbing Materials

Theoretical design is an important part of the research in microwave absorbing materials. Reasonable theoretical design can remarkably improve the efficiency of experimental work and decrease the cycle time of production. Research progress in theoretical designs of microwave absorbing materials is introduced through three levels: fitting of the effective electromagnetic parameters, computation of multilayer materials and optimization of design. With the rising of nano microwave absorbing materials, theoretical designs of microwave absorption need further development to satisfy the demands of practical applications.
