SUMMARY
Beam control is necessary in many terahertz (THz) applications. It is currently achieved by means of parabolic mirrors and refractive optics. However, diffraction optics presents game-changing capabilities because it can be used for spatial transformation of the beam. To fulfill the need for diffraction optics operating in THz range, we have developed a method for calculation and manufacturing of THz Fresnel lenses.
