Researchers have successfully demonstrated the use of #metasurfaces as a superior way to focus #ExtremeUltraviolet (#EUV) light. Their paper highlights the use of holes in a silicon membrane to efficiently #vacuum-guide light around the 50-nm wavelength.

This seems like a promising approach: a bit of physics informed and has flavor of DDA.

'a Graph Neural Networks (GNN) architecture which learns to model #electromagnetic scattering, can be applied to metasurfaces of arbitrary sizes. Most importantly, it takes into account the coupling between scatterers. Using this approach, near-fields of #metasurfaces with dimensions spanning hundreds of times the wavelength can be obtained in seconds.' #photonics #GNN #MachineLearing

#Chirality of #BioMolecules (left/right-handedness) is central to life. Light can be chiral too, a tool to interact with them. Light can also excite spins in #2dSemiconductors and rotate objects. #Nanophotonics can enhance these very weak effects. We surprisingly found that different phenomena, all relying on chirality of light, are incompatible! And found design rules for #metasurfaces for enhancing different chiral interactions (led by @albertogcurto).
