Near-field electromagnetic trapping of particles is generally obtained bymeans of gradient forces. In this paper,

Near-field electromagnetic trapping of particles is generally obtained bymeans of gradient forces. In this paper,
we discuss the attractive behavior of curl-spin forces, as well as their potential for near-field electromagnetic
trapping and manipulation. It is demonstrated that curl-spin forces enable the trapping of particles operating at
their resonant frequency. Such phenomena can be exploited to design more efficient and selective electromagnetic
traps, to boost near-field energy exchange systems, and to bring stability to coupled resonant radiators. It also is
illustrated how the balance between the gradient, radiation pressure, and curl-spin force components leads to the
formation of zero-force rings around their sources, which explicitly demarcate the trapping regions. Analytical
and numerical analyses are presented to assess the stability of the trapping mechanism. [--]
