Abstract
A nulling source with the cooling dielectric tube with narrow-width parabolic cylinders was developed to enhance range of the nulling angle in the FN-PMMW Imaging. High contrast PMMW images is obtained using proposed forward-nulling passive millimeter wave (FN-PMMW) imaging method with wide nulling angle range of up to 32°. Also the geometry will be suitable for the flow of people at the airport security check. Although one side of the nulling source is developed, the configuration of multi-side nulling source will be useful to increase the contrast.
