Abstract
Metasurfaces can flexibly regulate terahertz wave, but most of reported results are limited to single polarized terahertz wavefront manipulation. In this article, the propose metasurface can manipulate linearly polarized and circularly polarized terahertz waves. It consists of five metal layers (namely metal rectangular bars, metal rings, two orthogonal metal gratings, and I-shaped metal layers) separated by four polyimide dielectric layers. For circularly polarized wave incidence, the metasurface generates vortex beams with topological charges of l = ± 1 and l = ± 2 at frequency of 1.2 THz. In addition, the metasurface achieves “T” shaped near-field image at 0.931 THz. Under linearly polarized wave incidence, the metasurface produces polarization conversion with a conversion ratio over 98% within the frequency range of 0.6–0.8 THz. The proposed structure has potential application prospects in terahertz wave multi-polarized manipulation in future terahertz wireless communication.
期刊介绍：
he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered.
In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
