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.

Dynamic power-gating for leakage power reduction in FPGAs Research Article

Hadi JAHANIRAD,h.jahanirad@uok.ac.ir

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4, Pages 582-598 doi: 10.1631/FITEE.2200084

Abstract: devices have become widespread in electronic systems due to their low design costs and reconfigurability. In battery-restricted applications such as handheld electronics systems, low-power FPGAs are in great demand. almost equals dynamic power in modern integrated circuit technologies, so the reduction of leads to significant energy savings. We propose a power-efficient architecture for static random access memory (SRAM) based FPGAs, in which two modes (active mode and sleep mode) are defined for each module. In sleep mode, ultra-low is consumed by the module. The module mode changes dynamically from sleep mode to active mode when module outputs evaluate for new input vectors. After producing the correct outputs, the module returns to sleep mode. The proposed circuit design reduces the consumption in both active and sleep modes. The proposed low-leakage FPGA architecture is compared with state-of-the-art architectures by implementing Microelectronics Center of North Carolina (MCNC) benchmark circuits on FPGA-SPICE software. Simulation results show an approximately 95% reduction in consumption in sleep mode. Moreover, the total power consumption (leakage+dynamic power consumption) is reduced by more than 15% compared with that of the best previous design. The average area overhead (4.26%) is less than those of other designs.

Ionic Elastomers for Electric Actuators and Sensors Review

Chenrun Feng, C.P. Hemantha Rajapaksha, Antal Jákli

Engineering 2021, Volume 7, Issue 5, Pages 581-602 doi: 10.1016/j.eng.2021.02.014

Abstract:

In the past decades, ion conductive polymers and elastomers have drawn worldwide attention for their advanced functions in batteries, electroactive soft robotics, and sensors. Stretchable ionic elastomers with dispersed soft ionic moieties such as ionic liquids have gained remarkable attention as soft sensors, in applications such as the wearable devices that are often called electric skins. A considerable amount of research has been done on ionic-elastomer-based strain, pressure, and shear sensors; however, to the best of our knowledge, this research has not yet been reviewed. In this review, we summarize the materials and performance properties of engineered ionic elastomer actuators and sensors. First, we review three classes of ionic elastomer actuators—namely, ionic polymer metal composites, ionic conducting polymers, and ionic polymer/carbon nanocomposites—and provide perspectives for future actuators, such as adaptive four-dimensional (4D) printed systems and ionic liquid crystal elastomers (iLCEs). Next, we review the state of the art of ionic elastomeric strain and pressure sensors. We also discuss future wearable strain sensors for biomechanical applications and sports performance tracking. Finally, we present the preliminary results of iLCE sensors based on flexoelectric signals and their amplification by integrating them with organic electrochemical transistors.

A Smart Metasurface for Electromagnetic Manipulation Based on Speech Recognition Article

Lin Bai, Yuan Ke Liu, Liang Xu, Zheng Zhang, Qiang Wang, Wei Xiang Jiang, Cheng-Wei Qiu, Tie Jun Cui

Engineering 2023, Volume 22, Issue 3, Pages 185-190 doi: 10.1016/j.eng.2022.06.026

Abstract:

In this work, we propose and realize a smart metasurface for programming electromagnetic (EM) manipulations based on human speech recognition. The smart metasurface platform is composed of a digital coding metasurface, a speech-recognition module, a single-chip computer, and a digital-to-analog converter (DAC) circuit, and can control EM waves according to pre-stored voice commands in a smart way. The constructed digital metasurface contains 6 × 6 super unit cells, each of which consists of 4 × 4 active elements with embedded varactor diodes. Together with the DAC and single-chip computer, the speech-recognition module can recognize voice commands and generate corresponding voltage sequences to control the metasurface. In addition, a genetic algorithm (GA) is adopted in the design of the metasurface for efficiently optimizing the phase distributions. To verify the performance of the smart metasurface platform, three typical functions are demonstrated: radar cross-section reduction, vortex beam generation, and beam splitting. The proposed strategy may offer a new avenue for controlling EM waves and establishing a link between EM and acoustic communications.

PAM-Expanded Streptococcus thermophilus Cas9 C-to-T and C-to-G Base Editors for Programmable Base Editing Article

Hongyuan Zhang, Yifei Zhang, Wei-Xiao Wang, Weizhong Chen, Xia Zhang, Xingxu Huang, Wei Chen, Quanjiang Ji

Engineering 2022, Volume 15, Issue 8, Pages 67-77 doi: 10.1016/j.eng.2022.02.013

Abstract:

New therapeutic strategies for the rapid and effective treatment of drug-resistant tuberculosis are highly desirable, and their development can be drastically accelerated by facile genetic manipulation methods in Mycobacterium tuberculosis (M. tuberculosis). Clustered regularly interspaced short palindromic repeat (CRISPR) base editors allow for rapid, robust, and programmed single-base substitutions and gene inactivation, yet no such systems are currently available in M. tuberculosis. By screening distinct CRISPR base editors, we discovered that only the unusual Streptococcus thermophilus CRISPR associated protein 9 (St1Cas9) cytosine base editor (CBE)—but not the widely used Streptococcus pyogenes Cas9 (SpCas9) or Lachnospiraceae bacterium Cpf1 (LbCpf1) CBEs—is active in mycobacteria. Despite the notable C-to-T conversions, a high proportion of undesired byproducts exists with St1Cas9 CBE. We therefore engineered St1Cas9 CBE by means of uracil DNA glycosylase inhibitor (UGI) or uracil DNA glycosylase (UNG) fusion, yielding two new base editors (CTBE and CGBE) capable of C-to-T or C-to-G conversions with dramatically enhanced editing product purity and multiplexed editing capacity in Mycobacterium smegmatis (M. smegmatis). Because wild-type St1Cas9 recognizes a relatively strict protospacer adjacent motif (PAM) sequence for DNA targeting, we engineered a PAM-expanded St1Cas9 variant by means of structureguided protein engineering for the base editors, substantially broadening the targeting scope. We first developed and characterized CTBE and CGBE in M. smegmatis, and then applied CTBE for genome editing in M. tuberculosis. Our approaches significantly reduce the efforts and time needed for precise genetic manipulation and will facilitate functional genomics, antibiotic-resistant mechanism study, and drugtarget exploration in M. tuberculosis and related organisms.
