Abstract

We present a microwave absorber hybrid structure consists with nine different elements. Computer simulation demonstrates that this structure has successfully extended near perfect absorbance bandwidth at 6GHz-7GHz. Theoretical analysis has been made on the magnetic responses of tandem and parallel mixed modes in the structure. H-field distributions and permeability properties of the hybrid structure indicate that the tandem arrangement realizes multiple perfect absorption peaks and the parallel mixed mode combines discrete peaks into a broadband. The absorption band is proved to be involved with different magnetic resonance couplings.
