Paper Abstract

In this paper, we show the fabrication of metamaterials by 3D printing, metal coating and wet etching. We showcase 3D printed cylindrical metamaterial arrays with Terahertz frequency response around 200 GHz. We use two distinctive methods for metal coating - stamping and another involving sputtering followed by etching. We also represent a novel method of metamaterial fabrication by embedding metamaterial arrays in a curved parabolic substrate. This is achieved by simply printing a curved substrate followed by sanding and Polyurethane coating for smoothness. This followed by shadow printing metamaterial pattern using a stencil. Such a curved parabolic metamaterial shows both focusing and frequency selective performance around 100 GHz. Suite of fabrication approaches listed here will enable fabrication of complex 3D printed metamaterials for high frequency applications.
