Metric Options: CountsSelecting 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
This paper presents a high-sensitivity dual-open microchannel PCF-SPR refractometric sensor that was numerically analyzed using the Finite Element Method (FEM). A dual-open microchannel was created on both sides of the fiber to facilitate analyte infiltration and improve its detection performance. The microchannel of PCF was coated with gold plasmonic material to achieve practical sensing. The results revealed that the refractive index sensing range of the proposed refractometric sensor is between 1.37 and 1.43, with a highest amplitude sensitivity of 3743.64 RIU −1 and a wavelength sensitivity of 33000 nm/RIU. Additionally, it offers a maximum resolution of 5.56 × 10 −6 RIU. All structure parameters, such as air-hole length, pitch, open-channel radius, and gold thickness, are optimized. The proposed sensor is a significant improvement in the detection of multiple analytes in bio-sensing applications.
