摘要: Computer-generated holograms [1] can be applied in space terahertz technology; they are particularly suitable as focusing elements compact test ranges, for example, testing of high-gain antennas [2,3,4] and measuring radar cross section (RCS) scaled models [5]. Radio have also been demonstrated other millimeterand submillimeter-wave beam-shaping applications, such the creation non-diffracting mm-wave Bessel beams, vortices, custom-designed beam patterns [6,7,8].
