Optimal bounds for the generalized Euler–Mascheroni constant
Autor: Ti-Ren Huang, Bo-Wen Han, Xiao-Yan Ma, Yu-Ming Chu
Publikováno v: Journal of Inequalities and Applications, Vol 2018, Iss 1, Pp 1-9 (2018)
Abstract We provide several sharp upper and lower bounds for the generalized Euler–Mascheroni constant. As consequences, some previous bounds for the Euler–Mascheroni constant are improved.

Autor: Si Jia Li, Bo Wen Han, Zhuo Yue Li, Xiao Bin Liu, Guo Shai Huang, Rui Qi Li, Xiang Yu Cao
Publikováno v: Optics express. 30(15)
The Pancharatnam-Berry (PB) phase can be used to control the phase of circularly polarized electromagnetic waves. However, there are few studies on the modulation of dual-circularly polarized multi-beam using the transmissive coding metasurface. A sc

Design of Transmission Polarization Metasurface Converter
Autor: Bo Wen Han, Si Jia Li, Xiang Yu Cao, Jun Gao
Publikováno v: Materials Science Forum. 1035:718-723
The transmission polarization metasurface converter is an effective method to realize the polarization manipulation of the transmission waves, and it is also the research hotspot of metasurfaces. A new broadband transmissive polarization converter wa
