Abstract

We investigate the performance of various image reconstruction algorithms for the design of a metamaterial aperture-based imaging system. The metamaterial imaging system consists of a transmitting metamaterial aperture panel and a receiving low-gain probe antenna. Imaging of a 3 cm resolution target is performed using a number of reconstruction algorithms, including pseudo-inverse, matched filter, conjugate gradient squares (CGS), and two-step iterative shrinkage/thresholding (TwIST) methods. The differing quality of the resulting reconstructed images is shown as a function of these reconstruction techniques.
