Claims

C1strongest claim

We show that in a cross-beam configuration, where the radiation-pressure contribution is suppressed, the optical force can be changed for almost 2π in a wide range of particle sizes that provides a route toward optical sorting of resonant nanoparticles.

C2weakest assumption

The assumption that interference between electric and magnetic dipole moments produces highly directional scattering into both free-space and SPP channels whose angular directivity directly determines the direction and magnitude of the scattering-induced force, and that the cross-beam geometry fully suppresses radiation-pressure contributions without introducing other uncontrolled effects.

C3one line summary

Interference of electric and magnetic dipoles in Mie particles near metal surfaces produces directional scattering that tunes scattering-induced optical forces over almost 2π in cross-beam configurations, enabling resonant nanoparticle sorting.
