Improving the demultiplexing performances of the multiple Bessel Gaussian beams (mBGBs)
Results in Physics, 2021 As approximate non-diffracted beams, Bessel Gaussian (BG) beams are more suitable to be used in free-space optical (FSO) communication system than Laguerre Gaussian (LG) vortex beams because of its self-recovering property. However, due to the limitation
