对单个亚微米大小的金颗粒由渐逝场引起的辐射压力进行了实验分析。力测量基于使用三维位置传感技术对布朗运动进行热力学分析。横向辐射压力可归因于散射力，其方向与入射激光束的传播矢量相同。纵向的电势分布表明金颗粒被梯度力吸引到倏逝场的高强度区域。
Radiation pressure induced by an evanescent field was experimentally analyzed for a single submicrometer-sized gold particle. The force measurement was based on a thermodynamic analysis of Brownian motion by use of a three-dimensional position-sensing technique. The lateral radiation pressure could be ascribed to a scattering force, which was oriented in the same direction as the propagation vector of the incident laser beam. The potential profile in the longitudinal direction indicated that the gold particle was attracted to the high-intensity region of the evanescent field by a gradient force.
