A Low-Cost Two-Dimensional Near-Field Imaging System Based on a Goubau Line

A low-cost two-dimensional near-field compressive sensing system based on a dispersive surface-wave transmission line is presented. Unlike other existing imaging/sensing methods, only two transceivers are used in our proposed system. A frequency diversity based scheme is employed to accurately solve the sensing/imaging problem, with a high sub-wavelength resolution. Experimental results are present, which confirm the validity of our model and approach.
