Super-Diffraction Longitudinally Polarized Optical Needle With Ultra-Long Focal Depth Generated by a Radially Polarized High-Dimensional Circular Hollow Sinh-Gaussian Beam

In this paper, the incident beam called high-dimensional circular hollow sinh-Gaussian (HD-CHsG) beam with a novel wavefront is proposed, which is determined by three parameters (<italic>m</italic>, <italic>&#x03C3;</italic><sub>0</sub>, <italic>&#x0...
