High Efficiency Polarization-Independent Slanted Grating for RGB Bands

Autor: Ge Jin, Weicheng Liu, Zonghao Ye, Wei Jia, Yongfang Xie, Changhe Zhou

Publikováno v: IEEE Photonics Journal, Vol 13, Iss 4, Pp 1-8 (2021)

We proposed a slanted grating suitable for RGB bands which is polarization-independent and has a high diffraction efficiency of −1st order under normal incidence. We used Rigorous Coupled Wave Analysis (RCWA)and simulated annealing (SA) algorithm t

Autor: Yuda Chen, Jin Wang, Yihan Wang, Xingxue Li, Ge Jin, Changhe Zhou

Publikováno v: Applied Sciences, Vol 13, Iss 4, p 2270 (2023)

Diffraction gratings play an increasingly important role in various planar optical systems, such as near-eye display systems for virtual reality (VR) and augmented reality (AR). The slanted gratings have more advantages than other elements. A 1 × 2

High-Efficiency Broadband Polarization-Independent Reflective Grating with Double-Layer Dielectric Rectangle Groove in Littrow Mounting

Autor: Ge Jin, Wei Jia, Bayanheshig, Yongfang Xie, Changhe Zhou

Publikováno v: Applied Sciences, Vol 12, Iss 17, p 8612 (2022)

The design and performance of a high-efficiency broadband and polarization-independent reflective grating is reported. The physical mechanism of the gratings can be described by the modal method. By using rigorous coupled wave analysis (RCWA) and sim

The effect of head movement on the bounding gait of a quadruped robot with an active spine

Autor: Dongliang Chen, Chen Gong, Fuze Xing, Changhe Zhou, Mengfei Qi, Lianfu Wang

Publikováno v: Advances in Mechanical Engineering, Vol 11 (2019)

It is a common phenomenon in the movement of the quadruped mammals accompanied with head swings. Inspired by this, this article attempts to add head motion to the bounding gait of a quadruped robot. According to the theoretical analysis, there are tw

AvrRxo1 Is a Bifunctional Type III Secreted Effector and Toxin-Antitoxin System Component with Homologs in Diverse Environmental Contexts.

Autor: Lindsay R Triplett, Teja Shidore, John Long, Jiamin Miao, Shuchi Wu, Qian Han, Changhe Zhou, Hiromichi Ishihara, Jianyong Li, Bingyu Zhao, Jan E Leach

Publikováno v: PLoS ONE, Vol 11, Iss 7, p e0158856 (2016)

Toxin-antitoxin (TA) systems are ubiquitous bacterial systems that may function in genome maintenance and metabolic stress management, but are also thought to play a role in virulence by helping pathogens survive stress. We previously demonstrated th
