In this project, we developed and demonstrated the design, fabrication, and experimental characterization of a millimeter wave imaging system. To achieve these goals we employed our electromagnetic modeling expertise to design and refine the system specifications. A novel two-element all-diffractive millimeter wave imaging system has been implemented to significantly reduce the overall size and weight of the system while maintaining mission criteria. We also set up a new and dedicated mmW characterization and testing system. The new test platform with a capability of 3D vector-based near field scanning allows us to fully characterize and simulate mmW radiation. Based on this testing system, the in-house fabricated diffractive mmW lens has been characterized and shown to have diffraction limited performance, which results in a demonstrated capability for mmW imaging. In addition, we investigated two broadband frequency-independent antennas conical and planar spiral antennas, which offer possible integration into the mmW imaging system. Detailed achievements and progress made during the course of this effort are presented in this report.
