Physicists have managed to create an experimental structure with a strong toroidal dipole response of the electromagnetic field over a wide frequency range. This response is associated with a special configuration of electromagnetic currents causing high concentration of the field. A special dielectric metal lattice was created to produce and measure the response. The results can be used to create non-scattering materials, as well as to control electromagnetic fields. The research was published in Advanced Optical Materials.
