Abstract: In this paper, we introduce a covered dielectric layer in the traditional metamaterial absorber (MA) constructed by periodic resonant split rings. The absorber frequency can be simply controlled by the permittivity and the thickness of the added layer, without affecting the shape of the absorptivity spectrum. Furthermore, the dielectric loss property of the added layer does not influence the absorption characteristic obviously when the loss is not high. Based on these unique properties, a dynamically tunable MA can be realized by modulating a covered liquid dielectric layer. © 2011 American Institute of Physics.
