Assembly and co-occurrence patterns of rare and abundant bacterial sub-communities in rice rhizosphere soil under short-term nitrogen deep placement
Autor: Gui-long LI, Meng WU, Peng-fa LI, Shi-ping WEI, Jia LIU, Chun-yu JIANG, Ming LIU, Zhong-pei LI
Publikováno v: Journal of Integrative Agriculture, Vol 20, Iss 12, Pp 3299-3311 (2021)
Nitrogen (N) deep placement has been found to reduce N leaching and increase N use efficiency in paddy fields. However, relatively little is known how bacterial consortia, especially abundant and rare taxa, respond to N deep placement, which is criti

In-Band SCS Reduction of Microstrip Phased Array Based on Impedance Matching Network
Autor: Jun Hu, Peng-Fa Li, Shiwen Yang, Shi-Wei Qu
Publikováno v: IEEE Transactions on Antennas and Propagation. 70:330-340
A novel method to reduce in-band scattering cross section (SCS) of a phased array while maintaining high radiation performance is proposed in this paper, by using a special impedance matching network. The optimum load impedance curves of a phased arr

60 GHz Dual-Polarized High-Gain Planar Aperture Antenna Array Based on LTCC
Autor: Peng-Fa Li, Quan Xue, Shaowei Liao, Shi-Wei Qu
Publikováno v: IEEE Transactions on Antennas and Propagation. 68:2883-2894
Novel designs of planar aperture antenna (PAA) arrays are proposed in this article, which achieve dual-polarized and high-gain performances in the 60 GHz unlicensed band. In order to achieve high gain, the original PAA is expanded to its two-dimensio

Simplified Modeling of Wireless Power Transmission Problem Based on Focused Array Antenna
Autor: Peng-Fa Li, Shi-Wei Qu
Publikováno v: 2021 International Applied Computational Electromagnetics Society (ACES-China) Symposium.
A simplified model of wireless power transmission (WPT) system, which consists of a phased array as transmitter and a single antenna as receiver, is theoretically analyzed in this paper. The maximum transmission coefficient is given, as well as optim
