Room-temperature unidirectional routing of valley excitons of monolayer WSe2 via plasmonic near-field interference in symmetric nano-slits

Autor: Wen Xinglin, Zhou Yunxi, Chen Sijie, Yao Wendian, Li Dehui

Publikováno v: Nanophotonics, Vol 12, Iss 17, Pp 3529-3534 (2023)

Due to the short valley polarization time, it is hardly to separate opposite valley pseudospin of transition metal dichalcogenides (TMDs) for their practical applications in valleytronics. Coupling TMDs to unidirectional surface plasmon polariton (SP

Benchmark experimental study on wave run-ups of fixed four-rounded-square-column array in regular waves

Autor: Jing Liu, Longfei Xiao, Lijun Yang, Jun Li, Yufeng Kou

Publikováno v: Journal of Ocean Engineering and Science, Vol 7, Iss 5, Pp 419-430 (2022)

Wave run-up on surface-piercing columns is an important phenomenon in offshore engineering. Previous studies have mainly focused on a single column and circular column arrays. This study is concerned with the wave run-up ratio and the wave force on a

Enhanced Near-Field Interference Suppression Scheme for the Non-Cooperative Underwater Acoustic Pulse Detection of the Towed Linear Array

Autor: Kun Wei, Shiliang Fang, Jun Tao

Publikováno v: Journal of Marine Science and Engineering, Vol 10, Iss 2, p 250 (2022)

Near-field interference suppression for a towed linear array (TLA) is investigated in this paper. The existing eigencomponent association (ECA) scheme and multiple signal classification interference suppression (MUSIC-IS) scheme require the prior inf

A Sparse Perspective for Direction-of-Arrival Estimation Under Strong Near-Field Interference Environment

Autor: Longhao Qiu, Tian Lan, Yilin Wang

Publikováno v: Sensors, Vol 20, Iss 1, p 163 (2019)

Direction of arrival (DOA) estimation via sensor array is a crucial component of any passive sonar signal processing technology. In certain practical applications, however, the interested far-field targets are frequently affected by near-field interf

Optical nanoantennas are well-known for the confinement of light into nanoscale hot spots, suitable for emission enhancement and sensing applications. Here, we show how control of the antenna dimensions allows tuning the local optical phase, hence tu
