Complex Impacts of Wars on Global Sustainable Development in a Metacoupled World
I-GUIDE Forum 2023: Harnessing the Geospatial Data Revolution for Sustainability Solutions, 2023Wars and armed conflicts have had profound impacts on local and global sustainable development in an interconnected world. However, evidence on the impacts of wars is fragmented and little attention has been paid to the impacts on the 17 UN’s Sustainable Development Goals (SDGs), a unifying framework for achieving global sustainable development.

Metacoupling supply and demand for soil conservation service
Current Opinion in Environmental Sustainability, 2018To date most soil conservation service studies heavily focus on measuring soil conservation service supply from the natural system without considering corresponding beneficiaries (i.e. demand), and feedback from the human system. In this paper, we presented an updated soil conservation service assessment framework as a two-way analysis of supply and ...

Efficient Metacoupler for Complex Surface Plasmon Launching
Advanced Optical Materials, 2018AbstractSurface plasmons (SPs) promise versatile potential applications in many aspects and thus have been a subject of enormous interest. As the most essential functionality, efficient coupling of free‐space light into complex SP field is of particular interest in current research.

Pathways for achieving conservation targets under metacoupled anthropogenic disturbances
Journal of Environmental ManagementEnhancing connectivity between protected areas stands as a paramount objective in advancing global conservation goals, particularly in coastal regions grappling with escalating human disruptions. However, little attention has been given to quantitative assessment of human-nature interactions within and among protected areas.

High-performance polarization-controlled terahertz spoof surface plasmon polaritons metacoupler
2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019In this paper, a linear polarization-controlled (LPC) spoof surface plasmon polaritons (SSPPs) meta-coupler with high efficiency and directionality is proposed and demonstrated in the terahertz (THz) regime. By changing the polarization (TE or TM polarization) of the incident electromagnetic (EM) waves, the corresponding SSPPs can be directionally ...

Applied Physics Letters, 2019
A natural diamond surface was nanopatterned in a subablative scanning mode by multiple tightly focused 515-nm, 300-fs laser pulses, resulting in regular surface metagratings (nanoripples) with a subwavelength period of Λ ∼ 100 nm, an almost undistorted crystalline structure, free from sp2-carbon, oriented perpendicular to the laser polarization, and ...

P‐47: Multi‐wavelength achromatic metacoupler for augmented reality display using adjoint method
SID Symposium Digest of Technical PapersDiffractive waveguides are a promising optical combiner technology for augmented reality (AR) as they provide the potential for the slimmest geometry and lightest weight. However, their severe chromatic aberration imposes a big challenge for full‐color display applications.
