| description | •Absorption peak is changed with structural parameters.•Absorption peak is tunable with the measured temperature.•Original absorption performance is maintained.
The design and development of resonance-tunable and high-absorptivity metamaterial absorbers is a research hotspot. In this paper, a single-band tunable metamaterial absorber based on the strontium titanate (STO) layer is designed and measured. This absorption peak is enhanced from 90% (D=3.2μm) to 99.4% (D=4.2μm) and the resonant frequency point is shifted from 6.2 THz to 5.8 THz, while it is enhanced and shifted to lower frequencies with the structural parameter P reducing. Measured results show that this absorption peak shows only a 2% reduction when the measured temperature is increased from 300 K to 380 K. Synchronous, the resonant frequency point is shifted from 6.2 THz to 7.1 THz. Based on the temperature-dependence of the STO layer, a temperature tunable metamaterial absorber is experimentally verified. |
