Metamaterial Lensing Devices

Abstract

In recent years, the development of metamaterials and metasurfaces has drawn great attention, enabling many important practical applications. Focusing and lensing components are of extreme importance because of their significant potential practical applications in biological imaging, display, and nanolithography fabrication. Metafocusing devices using ultrathin structures (also known as metasurfaces) with superlensing performance are key building blocks for developing integrated optical components with ultrasmall dimensions. In this article, we review the metamaterial superlensing devices working in transmission mode from the perfect lens to two-dimensional metasurfaces and present their working principles. Then we summarize important practical applications of metasurfaces, such as plasmonic lithography, holography, and imaging. Different typical designs and their focusing performance are also discussed in detail.

Massive metamaterial system-loaded MIMO antenna array for 5G base stations

“…Metamaterial (MTM), as an artificial medium, has several unusual features, such as negative (refractive index, permeability, and permittivity), making it appropriate for a variety of applications, including absorber 18 , bio sensing 19 , microwave imaging 20 , antennas 21 , metamaterial coding 22 , metamaterial lensing 23 , terahertz metamaterial 24 , and microwave devices like GPS5, WiMAX 25 .…”

Design and Analysis of wide bandwidth Quad ‘e’ mirror-shaped metamaterial for Wi-Fi and Satellite Applications

“…Metamaterial, which consists of either negative permeability or negative permittivity can be classified as a single negative (SNG) metamaterial (Srinivasan et al 2019). The spread of metamaterial research, which revealed the MTMs unique characteristics such as negative permittivity (ε), negative permeability (µ) and negative refractive index (n), has led to a wide range of applications in microwave and optical regime such as reconfigurable antenna (Zhang et al 2019), satellite (Mao et al 2017), invisibility cloaking (Jing et al 2020), filters (Ahamed et al 2020) and superlenses (Lv et al 2019) etc. MTMs have recently originated with utilization in various frequency bands, as every frequency band has a diverse range of applications.…”
