Electromagnetic forces on a discrete concentrator under time-harmonic illumination

Patrick Chaumet
Sébastien Guenneau

Résumé

We study electromagnetic forces and torques experienced on both perfect and discretized transformation-based concentrators, under time-harmonic illumination. The effect of the concentration is investigated in both cases and compared to the case of a perfect cloak. The effect of a Lorentz dispersion model on the optical force and torque is also investigated, and the force experienced by a dielectric particle located at the center of the concentrator is studied.
