About the Cover
The image on the cover represents the interactions of a flat spiral shaped particle with an incident beam of light. From the perspective of spatial symmetries, this spiral is not a geometrical chiral object. However, thanks to the framework developed in the article “ Spatial symmetries in nonlocal multipolar metasurfaces” by Karim Achouri, Ville Tiukuvaara, and Olivier J.F. Martin, it can be demonstrated that the particle nonetheless exhibits pseudochiral responses in the form of quadrupolar contributions.
