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.

Correspondence: A low-profile dual-polarization programmable dual-beam scanning antenna array Perspective

Shichao ZHU, Yuanfan NING, Hongbo CHU, Pei XIAO, Gaosheng LI,Gaosheng7070@vip.163.com

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 10, Pages 1504-1512 doi: 10.1631/FITEE.2300253

Abstract: A low-profile dual-polarization dual-beam scanning antenna array based on holographic control theory is presented in this paper. The radiating elements are ingeniously designed to achieve reconfigurable polarization and modulation of the radiation phase by controlling the state of the PIN diodes integrated on each element. A 72-channel series-parallel equal-amplitude and in-phase feeding network is integrated with the radiating array to achieve low-profile characteristics. The two-dimensional (2D) dynamic and accurate deflection of the beam is achieved by a designed direct current (DC) bias circuit that digitally encodes the antenna array using the single-chip microcontroller. A 2-element subarray and a 6×12 array have been fabricated and the digitally controllable radiation pattern of this antenna system has been experimentally verified. The antenna system can achieve the beam scanning of -30° to 30° with a step-scan of 5° at 11 GHz. The proposed antenna system is characterized by low profile, low cost, easy integration, and accurate beam steering, and holds broad application prospects in radar systems, smart antennas, and other fields.

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.
