Polylactic acid (PLA) is the most widely used raw material in extrusion-based three-
dimensional (3D) printing (fused deposition modeling, FDM approach) in many areas since …

Abstract Fused Deposition Modelling (FDM) is an additive manufacturing technique that is
widely used for the fabrication and prototy** of parts and objects of different shapes and …

This article covers recent advances in the fusion of metasurface antenna design and
computational imaging (CI) concepts for the realization of imaging systems that are planar …

In this paper, a novel, compact, high-gain, directive, and superstrate configuration-based
metasurface (MS) antenna has been designed, which incorporates a fractal-shaped slotted …

Abstract Three-dimensional (3D) printing is a new paradigm in customized manufacturing
and allows the fabrication of complex optical components and metaphotonic structures that …

In this paper, we present a two-dimensional dynamic metasurface aperture to perform
computational polarimetric microwave imaging for the first time. First, a novel tunable dual …
