Diffractive Elements for Zero-Order Bessel Beam Generation With Application in the Terahertz Reflection Imaging
Novel diffractive elements are presented to produce zero-order Bessel beams in the terahertz (THz) band. First, diffractive elements are designed as phase plates to change the direction of the incident Gaussian beam. Then, they are fabricated by the emerging three-dimensional printing technology. La...
