Abstract :
The characteristics of millimeter-wave Bessel beams generated by axicons are analyzed in our paper. The analysis method is to combine a two-dimension finite-difference time-domain (2-D FDTD) method for rigorous electromagnetic computation with a Stratton-Chu formulas for determining electromagnetic fields in the far field. The analysis results and conclusions are given.
