Focusing and Wavefront Splitting of an Extreme Ultraviolet Laser with a Tubular Optical Element
Photonics, 2023 A capillary discharge extreme ultraviolet laser is focused and wavefront split at 46.9 nm by a tubular optical element. The reflectivity at 46.9 nm is both simulated and measured to be higher than 90% with a slight optical aberration.

Switchable Polarization Selective Terahertz Wavefront Manipulation in a Graphene Metasurface
IEEE Photonics Journal, 2019 We propose a graphene-based metasurface to investigate the function of switchable polarization selective wave manipulation in THz regime by using the finite-difference time-domain method. The proposed metasurface consists of two layers of graphene arrays,

Sea-Air Exchange of Methane in Shallow Inshore Areas of the Baltic Sea
Frontiers in Marine Science, 2021 We report sea-air fluxes of methane in physically and biologically distinct inshore habitats of the Baltic Sea with the goal to establish empirical relationships that allow upscaling of local site-specific flux measurements.
