Dielectric Metasurface Enabled Multispectral Polarisation Imaging
2025 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)Polarisation imaging is a technique used to enhance and distinguish objects and surface characteristics. In particular, it is used in agricultural drone and small-satellite applications such as for crop classification [1] and monitoring vegetation [2 ...

The influence of surface charge on the coalescence of ice and dust particles in the mesosphere and lower thermosphere [PDF]
Atmospheric Chemistry and Physics, 2021 Agglomeration of charged ice and dust particles in the mesosphere and lower thermosphere is studied using a classical electrostatic approach, which is extended to capture the induced polarisation of surface charge. Collision outcomes are predicted whilst
