Anapole states in GSP resonators are formed by the compensation of magnetic dipole moments, differing from dielectric particles.
These magnetic anapole states do not significantly suppress scattering but lead to substantial electric field enhancement.
Experimental verification of huge electric field enhancement was achieved.

Conclusions:

GSP resonators exhibit unique anapole states with significant electric field enhancement.
This property makes GSP resonators highly promising for applications in nonlinear harmonic generation, absorption enhancement, and sensing.
