Research on Broadband Microwave Absorber Containing a 2D Artificial Electromagnetic Material Composed of Cross Section Resonator Sub-Unit Cells Inserting Ferromagnetic Materials

This paper provides a new method to improve microwave absorption properties of ferromagnetic materials. A 2D artificial electromagnetic material is designed using a square combination of cross section resonator sub-unit cells, and then inserted into carbonyl iron powder layers to realize a broadband microwave absorber. Both the simulation and experiment results show that the absorber can realize the wideband and high efficiency absorption.
