Terahertz (THz) special beams have unique field distributions and diffraction characteristics, showing significant advantages in the applications of particle manipulation, optical imaging, and optical communications. Some recent researches of several groups, including ours, on THz special beams are reviewed herein, such as THz Bessel beam, vortex beam, Airy beam, bottle beam, and radially polarized beam. The field distributions, diffraction characteristics, and application prospects of these beams are systematically described. The aim herein is to discuss the effect of THz special beams to the advancement of THz technology.
