DOI: 10.1109/tap.2023.3270715
Abstract: We present a 3-D method to numerically design a realizable metasurface, which transforms a given incident field into a radiated field that satisfies mask-type (inequality) constraints. The method is based on an integral equation formulation,… read more here.

DOI: 10.1109/tgrs.2017.2679438
Abstract: To maintain sufficient signal-to-noise ratio (SNR) for image reconstruction and image interpretation, conventional synthetic aperture radar (SAR) systems must trade off resolution and scene size. This paper proposes a new SAR mode of operation, which… read more here.
