In this contribution we exploit the controlled reflection provided by metasurfaces together with holographic techniques to design non-profiled diffractive optical elements working at 334 GHz. The required metasurfaces are synthesized via an iterative algorithm, fabricated by photolithography and experimentally validated using a submillimeter-wave BWO spectrometer.
