Metamaterials: Reshape and Rethink Review

Ruopeng Liu, Chunlin Ji, Zhiya Zhao, Tian Zhou

Engineering 2015, Volume 1, Issue 2,   Pages 179-184 doi: 10.15302/J-ENG-2015036

Abstract:

Metamaterials are composite materials whose material properties (acoustic, electrical, magnetic, or optical, etc.) are determined by their constitutive structural materials, especially the unit cells. The development of metamaterials continues to redefine the boundaries of materials science. In the field of electromagnetic research and beyond, these materials offer excellent design flexibility with their customized properties and their tunability under external stimuli. In this paper, we first provide a literature review of metamaterials with a focus on the technology and its evolution. We then discuss steps in the industrialization process and share our own experience.

Design and analysis of electrothermal metasurfaces

Xiu LIU, Zhuo LI, Zexiao WANG, Hyeong Seok YUN, Sheng SHEN

Frontiers in Energy 2023, Volume 17, Issue 1,   Pages 134-140 doi: 10.1007/s11708-022-0841-9

Abstract: Electrothermal metasurfaces have garnered considerable attention owing to their ability to dynamically control thermal infrared radiation. Although previous studies were mainly focused on metasurfaces with infinite unit cells, in practice, the finite-size effect can be a critical design factor for developing thermal metasurfaces with fast response and broad temperature uniformity. Here, we study the thermal metasurfaces consisting of gold nanorods with a finite array size, which can achieve a resonance close to that of the infinite case with only several periods. More importantly, such a small footprint due to the finite array size yields response time down to a nanosecond level. Furthermore, the number of the unit cells in the direction perpendicular to the axis of nanorods is found to be insensitive to the resonance and response time; thus, providing a tunable aspect ratio that can boost the temperature uniformity in the sub-Kelvin level.

Microwave metamaterials: from exotic physics to novel information systems Review Articles

Rui-yuan WU, Tie-jun CUI

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 1,   Pages 4-26 doi: 10.1631/FITEE.1900465

Abstract: Metamaterials and metasurfaces have attracted much attention due to their powerful ability to control electromagnetic (EM) waves. In this paper, we review the recent developments in the field of EM metamaterials, starting from their exotic physics to their applications in novel information systems. First, we show the fundamental understanding on traditional metamaterials based on the effective medium theory and related applications, such as invisibility cloaks and meta-lenses. Second, we review the two-dimensional versions of metamaterials, i.e., metasurfaces, for controlling spatial waves and surface waves and thereafter present their typical designs. In particular, we briefly introduce spoof surface plasmon polaritons and their applications in microwave frequencies. Following the above approach, we emphatically present the concepts of digital coding metamaterials, programmable metamaterials, and information metamaterials. By extending the principles of information science to metamaterial designs, several functional devices and information systems are presented, which enable digital and EM-wave manipulations simultaneously. Finally, we give a brief summary of the development prospects for microwave metamaterials.

A Planar 4-Bit Reconfigurable Antenna Array Based on the Design Philosophy of Information Metasurfaces Article

Zheng Xing Wang, Hanqing Yang, Ruiwen Shao, Jun Wei Wu, Guobiao Liu, Feng Zhai, Qiang Cheng, Tie Jun Cui

Engineering 2022, Volume 17, Issue 10,   Pages 64-74 doi: 10.1016/j.eng.2022.03.019

Abstract:

Inspired by the design philosophy of information metasurfaces based on the digital coding concept, a planar 4-bit reconfigurable antenna array with low profile of 0.15 λ0 (where λ0 is the wavelength) is presented. The array is based on a digital coding radiation element consisting of a 1-bit magnetoelectric (ME) dipole and a miniaturized reflection-type phase shifter (RTPS). The proposed 1-bit ME dipole can provide two digital states of “0” and “1” (with 0° and 180° phase responses) over a wide frequency band by individually exciting its two symmetrical feeding ports. The designed RTPS is able to realize a relative phase shift of 173°. By digitally quantizing its phase in the range of 157.5°, additional eight digital states at intervals of 22.5° are obtained. To achieve low sidelobe levels, a 1:16 power divider based on the Taylor line source method is employed to feed the array. A prototype of the proposed 4-bit antenna array has been fabricated and tested, and the experimental results are in good agreement with the simulations. Scanning beams within a ±45° range were measured with a maximum realized gain of 13.4 dBi at 12 GHz. The sidelobe and cross-polarization levels are below –14.3 and –23 dB, respectively. Furthermore, the beam pointing error is within 0.8°, and the 3-dB gain bandwidth of the broadside beam is 25%. Due to its outstanding performance, the array holds potential for significant applications in radar and wireless communication systems.

Abstract: 精确的、与波长相关的相位调制在许多领域中是必不可少的，比如超分辨成像、全彩色全息、微纳加工以及光通讯。这一要求很难通过单一的传统光学元件实现，一般需要使用多个光学元件组合完成。本文提出一种可以实现波长选择性波前整形的超表面设计方法。具体来说，本文设计了一种超表面，它能够对785 nm波长的光做涡旋相位调制，同时不影响590 nm波长的光保持原有相位分布。本文通过干涉仪以及对应点扩散函数的测量来验证不同波长下的波前分布。与已提出的空间复用方式以及色散工程的方法相比，我们提出的设计方法更加直接，优化难度小，适用于需要波长选择性编码的光学系统。本文所提平面光学器件对于需要波长选择性编码的光学系统具有重要应用意义。
