Spatial symmetries in nonlocal multipolar metasurfaces

This cover illustrates a convenient and powerful theoretical framework connecting spatial symmetries to electromagnetic and scattering properties, thereby significantly simplifying the modelling procedure of metasurfaces.
This technique does not require any prior knowledge of group theory or complex numerical simulations, enabling to determine the properties of a metasurface scattering response, such as chirality or asymmetric transmission. (Advanced Photonics 2023, Vol. 5, Issue 4, 049901)
