Electromagnetic wave control by metasurfaces: From design to manufacturing

Spada, Luigi La; Hao, Yang

Abstract

Recently, there have been a new interest in controlling and manipulating electromagnetic waves in different frequency ranges. The development of new two-dimensional materials, called meta-surfaces, have been used to control and tailor the electromagnetic waves propagation properties. Several studies focused their attention on phase modulation, very few on amplitude. However, there have been no general design procedure able to control both of them at the same time. Therefore, the aim of this paper is to develop a robust design tool to manipulate the electromagnetic wave behavior over flat and 3D objects. The proposed approach will be used to design, manufacture and experimentally measure metasurface-based devices for lenses, cloaking, manipulation and bending applications. Good agreement between analytical, numerical, and experimental results has been achieved, proving that the realized devices are wideband, polarization independent, easy to fabricate and can be scaled in different frequency ranges from microwave to optics.
