Abstract

This paper introduces a nondiffraction Bessel beam launcher based on 3-dimensional (3-D) printed discrete dielectric lens operating at 0.3 THz. The designed thin dielectric lens can transform the quasi-Gaussian beam from a commercially available feed horn into a well collimated and confined pseudo-Bessel beam. Moreover, an in-housed developed 3-D printing technology is used to manufacture the designed terahertz lens aiming at simplifying the manufacturing process with low cost. Measured and simulated results demonstrate that the proposed lens can generate nondiffraction Bessel beam with a constant spot size and constant axial intensity over a considerable range at terahertz frequencies.
