摘要

研究了电磁辐照压力对接近表面等离子激元振动频率的球形金属纳米粒子的影响。在辐射压力的作用下，金属纳米粒子的极化率成为一个张量。推导了平面偏振光和圆偏振光两种情况下的共振压力分量表达式。我们已经证明共振压力可以在很大程度上取决于非球形纳米颗粒的形状及其和光传播方向和光偏振方向的方向。

Resonance pressure of electromagnetic radiation on metal nanoparticle

The influence of the electromagnetic irradiation pressure on a spheroidal metallic nanoparticle at the frequencies close to the surface plasmon vibrations has been considered. With the action of the radiation pressure, the polarizability of metal nanoparticle becomes a tensor quantity. The expressions for the resonance pressure components for the cases of plane-polarized and circularly polarized light have been derived. We have demonstrated that the resonance pressure can substantially depend on the shape of a non-spherical nanoparticle and its orientation with respect to the direction of light propagation and the light polarization.
