Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this paper, a triple-band terahertz metamaterial absorber composed of double rectangular patches connected by two identical gold strips is proposed and demonstrated. Simulation results show that the designed absorber can realize three discrete absorption peaks (labeled as A, B and C) with corresponding absorption rates of 99.21%, 91.75% and 96.12%. The physical mechanism of these absorption peaks is verified by the distribution of electric fields. Different numerical investigations on the proposed absorber are presented to explore the influence on the performance of the device. The application of the absorber in terms of the surrounding refractive index sensing is further discussed. It is found that the third resonance peak has an ultra-narrow line width of 0.0749 THz, sensitivity of 125 GHz/refractive index unit (RIU), quality factor (Q-factor) value of 32.7, and figure of merit of 1.66. These results mean that the suggested scheme has considerable applications in imaging, sensing, detecting and other terahertz-related regimes. The design can also be applied in other applications, such as silicon photovoltaics.
