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
We propose a novel orbital angular momentum (OAM) space division multiplexing system based on Lommel–Gaussian (LMG) beam, which utilizes different transverse wavenumbers under the same topological charge. Using the random phase screen method and diffraction theory, the evolution of light field and mode crosstalk are effectively analyzed during transmission. Owing to the non-diffracting feature, LMG beams are more robust than traditional Laguerre–Gaussian (LG) beams through spatial spectrum analysis under the same intensity. More importantly, the results show that the shape of demultiplexed spot is related to the symmetry of original OAM-carrying beam and LMG beams with smaller scaling factor are better for detection. This work is anticipated to open up new perspectives for future high-capacity communication missions.
