The dynamic toroidal multipoles were theoretically introduced in the 1970s in the context of a complete multipole expansion in electrodynamics and their radiation properties were studied in a series of theoretical works. The experimental study of dynamic toroidal multipoles, however, became possible only with advances in artificial electromagnetic materials (metamaterials), leading to the first experimental observation of the toroidal dipole, in 2010 in an array of microwave resonators with elements of toroidal symmetry.
