Studying the different coupling regimes for a plasmonic particle in a plasmonic trap

Olivier Martin, Jeonghyeon Kim

Plasmonic antennas improve the stiffness and resolution of optical tweezers by producing a strong near-field. When the antenna traps metallic objects, the optically-resonant object affects the near-field trap, and this interaction should be examined to est ...
