摘要:

通过类比的三维光学瓶光束,我们介绍了等离子体瓶光束:一个二维表面波的特点是晶格的等离子体瓶,即交替区域的明亮foenes包围低强度。二维瓶状光束是由无衍射光束、余弦高斯光束和平面波的干涉产生的,从而产生无衍射的复杂强度分布。通过控制余弦-高斯光束的传播常数,可以设计等离子体瓶的尺寸和数量。由这种新的等离子体波形成的热点的二维晶格可能在等离子体捕获中具有应用。

英文摘要:

By analogy to the three dimensional optical bottle beam, we introduce the plasmonic bottle beam: a two dimensional surface wave which features a lattice of plasmonic bottles, i.e. alternating regions of bright focii surrounded by low intensities. The two-dimensional bottle beam is created by the interference of a non-diffracting beam, a cosine-Gaussian beam, and a plane wave, thus giving rise to a non-diffracting complex intensity distribution. By controlling the propagation constant of the cosine-Gauss beam, the size and number of plasmonic bottles can be engineered. The two dimensional lattice of hot spots formed by this new plasmonic wave could have applications in plasmonic trapping.
