A Tunable Zig-Zag Reflective Elastic Metasurface
Crystals, 2022 In this paper, inspired by origami structures, we offer a very simple tuning method to overcome the limitations of general elastic metasurfaces, where only a certain functionality at a certain frequency range can be achieved, by designing a reflective ...

Focusing on Contraction. [PDF]
, 2013 Focusing [1] is a proof-theoretic device to structure proof search in the sequent calculus: it provides a normal form to cut-free proofs in which the application of invertible and non-invertible inference rules is structured in two separate and disjoint phases.

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.
