Abstract
Embodiments of a grey-scale holographic structure and system for generating a collimated wavefront in a compact range are generally described herein. In some embodiments, the grey-scale holographic structure comprising millimeter-wave transmissive material having a surface arranged to provide differing amounts of phase-delay to an incident millimeter-wave wavefront as the incident wavefront passes through the material. The grey-scale holographic structure may comprises a plurality of layers (N) to provide a phase total delay of lambda which results from a series tuned layers, each having a thickness of a wavelength/N. Each layer provides a predetermined amount of phase delay allowing the structure to operate as a phase-delay hologram.
