We report on the observation of a resonant electromagnetic response in an artificially engineered medium, or metamaterial, that cannot be attributed to magnetic or charge multipoles and can only be explained by the existence of a toroidal dipole. Our direct experimental evidence of the toroidal ...
Toroidal dipole一般翻译为环形矩，但是最近两年的文献已经正式推导出，它并不是独立于电偶极子（electric ...
toroidal dipole excitationCompared with the traditional electric and magnetic multipoles, the existence of a dynamic toroidal moment has received increasing interest in recent years. This is due to its novel electromagnetic response, including dynamic non-radiating charge-current configurations and non-...

Mie resonances such as electric dipole (ED) and magnetic dipole (MD) can be easily excited in all-dielectric metamaterial structures [13]. However, the excitation of toroidal dipole (TD) in these systems is still challenging. The TD can be viewed as a circular head-t...
This interesting field was set off by mimicking toroidal coils [52], [100] at microwave frequency to explore the toroidal dipole response in a great variety of structures as well as entering the optical regime by scaling structures down to the nanoscale [57]. Figure 4 gives a brief but not...
