摘要:

我们证明了实验的产生和近场成像的无衍射表面波-等离子体艾里光束,在金金属膜的表面上传播。Airy等离子体激元由工程纳米级相位光栅激发,并在其传播过程中表现出显着的光束弯曲。我们发现,所观察到的艾里等离子体表现出自我修复的特性,提出了新的应用等离子体电路和表面光学操纵。

英文摘要:

We demonstrate experimentally the generation and near-field imaging of nondiffracting surface waves - plasmonic Airy beams, propagating on the surface of a gold metal film. The Airy plasmons are excited by an engineered nanoscale phase grating, and demonstrate significant beam bending over their propagation. We show that the observed Airy plasmons exhibit self-healing properties, suggesting novel applications in plasmonic circuitry and surface optical manipulation.
