Jun 07, 2017 Generation of One-Dimensional Terahertz Airy Beam by Three-Dimensional Printed Cubic-Phase Plate Impact Statement In optical domain, Airy beams have been widely studied for their non-diffracting, self-bending and self-healing features. However, the THz Airy beams are difficult to demonstrate for the lack of efficient modulators.

The ideal Airy beam carries an infinite amount of energy, whereas in practice the Airy beam is truncated, having a finite energy. The finite Airy beam is obtained by multiplying the Airy function with an exponential or Gaussian window 4 .
metasurface is a material with a thickness less than the wavelength of the incident beam. It has characteristics of flattening and low loss. In this paper, we design a metasurface to generate an Airy beam with low loss and high effi-ciency using commercial software COMSOL. The characteristics of the resulting Airy beam are tested and verified.
