Abstract
We report the design, simulation, and measurement of a magnetic-type metamaterial absorber with needlepoint-shape pattern in the microwave region. Experimental result shows that the needlepoint-shape pattern expands the absorption bandwidth of the magnetic absorber by more than 65%, which is related to the LC resonances. Different from the non-magnetic metamaterial absorber, the power loss in the proposed absorber is dominated by magnetic loss. The dielectric loss and magnetic loss are both strengthened by the metamaterial resonance. The absorber has applications in the area of eliminating microwave energy.Keywords
