Influence of Buddhism on Traditional Chinese Culture If we observe traditional Chinese music from the perspective of the sociology of music instead of the morphology of music,and if we view music as a way of thinking and a cultural phenomenon instead of merely as a skill or a form,it is an appropriate way to classify Chinese traditional music into four categories,namely,folk music,court music,religious music,and literati music.Therefore,without the investigation into and research of Chinese religious music,we will fail to grasp the whole picture of Chinese traditional music.

Jamming Monitoring Technology of the Space Situational Awareness Facilities:A Comprehensive Survey

引用

Journal of Beijing institute of Technology 2022年第2期31卷 152-168页

Complicated electromagnetic environments of the space situational awareness facilities(i.e.,satellite navigation systems,radar)would significantly impact normal operations.Effective monitoring and the corresponding diagnosis of the jamming signals are essential to normal opera-tions and the innovations in anti-jamming equipment.This paper demonstrates a comprehensive survey on jamming monitoring algorithms and applications.The methods in dealing with jamming signals are summarized primarily.Subsequently,the jamming detection,identification,and direc-tion finding techniques are addressed separately.Based on the established studies,we also provide some potential trends of the demonstrated jamming monitoring issues.

A Novel Flexible Antenna at Very High Frequency Band for On-Body Applications

引用

Journal of Beijing institute of Technology 2022年第1期31卷 81-90页

作者： Abhishek Kandwal Huajie Tang Pengfei Ao kun Wang Jingzhen Li Yuhang Liu Tobore Igbe Zedong Nie Shenzhen institute of Advanced Technology Chinese Academy of SciencesShenzhen 518055China

This paper proposes a novel flexible antenna design operating at very high frequency(VHF)band for on-body applications such as human body communication(HBC).The antenna consists of back-to-back E-shaped fractal and complimentary structures designed over a thin flex-ible substrate.The overall design working on the principle of fractal geometries and capacitive coupling is highly beneficial to achieve better antenna characteristics even at low frequencies around 35 MHz-45 MHz that are being used for HBC application.The proposed antenna obtained a large bandwidth of around 10.0 MHz in air and a bandwidth of around 8.0 MHz during on-body opera-tion.The antenna has been tested in three different scenarios viz.air,on-body single antenna and on-body communication using two antennas.The insertion loss is reduced to a minimum in all three scenarios,which is quite beneficial for better signal transmission.The size miniaturization with high flexibility in such low frequencies has also been achieved in the paper that makes the proposed design suitable for human body communication applications.
