title = "3-D Printed Terahertz Lens for Generation of Non-diffractive Bessel Beam Carrying OAM",
abstract = "A novel 3-dimensional (3-D) printed lens for high-order Bessel beam generation operating at 300 GHz is proposed in this paper. The designed terahertz (THz) lens can transform the spherical wave-front from the feed horn into non-diffractive Bessel beam carrying orbital angular momentum (OAM). The lens consists of discrete dielectric posts, whose height can be tuned from pixel to pixel to realize the desired aperture phase distribution. Furthermore, 3-D printed technology is used to fabricate the lens with low cost. Measured results demonstrate that the designed 3-D printed lens can generate THz non-diffractive Bessel vortex beam carrying OAM.",
