Magnetically Reconfigurable Toroidal Metasurfaces In article number 2303045, Nityananda Acharyya, Dibakar Roy Chowdhury, and co-workers present a comprehensive study of the magnetically reconfigurable toroidal metasurfaces. Simultaneous magnetic tuning of electric dipole, toroidal dipole, and other higher-order multipoles is demonstrated experimentally as well as theoretically. Multipolar analysis reveals that the toroidal and dipole modes can be enhanced by almost 56% and 183%, respectively, under low intensity magnetic fields.
