Paper Abstract

Based on binary optical ideas, the beam shapers are designed for producing pseudo-Bessel beams at THz. In order to analyze precisely the properties of pseudo-Bessel beams generated by the designed shapers, a rigorous electromagnetic calculation method is employed. This is to associate a two-dimensional finite-difference time-domain (2-D FDTD) method, for determining the fields diffracted by the beam shapers in the near region, with Stratton-Chu formula (SCF), for compute the fields in the far region. The numerical results and conclusions are given in our paper.
