            Abstract : 
For the first time, we present measurement results of a small amplitude hologram operating at 650 GHz. The hologram transforms an incident spherical wave to a plane wave which can be used in a compact antenna test range (CATR). Preliminary measurement results are encouraging: they agree fairly well with simulations.
