对自成像Talbot效应的等离子体激元模拟进行了描述和理论分析。富含热点的等离子体地毯被证明是由一排周期性间隔的表面特征产生的。在金属膜上钻孔并从背面照明的一排孔作为这一概念的可实现的实施被讨论。在所考虑的例子中，所产生的行的自映像与原始的自映像之间的距离最大可达数百个波长。图像焦点的大小接近半个波长，可以通过改变外部照明的入射方向来控制光斑的位置，这意味着可以将这种效应(及其扩展到非周期表面特征)用于远场图案化以及等离子体电路、能量转移和相关现象中的长距离等离子体互连。(C)2007年美国光学学会。
The plasmon analog of the self-imaging Talbot effect is described and theoretically analyzed. Rich plasmon carpets containing hot spots are shown to be produced by a row of periodically-spaced surface features. A row of holes drilled in a metal film and illuminated from the back side is discussed as a realizable implementation of this concept. Self-images of the row are produced, separated from the original one by distances up to several hundreds of wavelengths in the examples under consideration. The size of the image focal spots is close to half a wavelength and the spot positions can be controlled by changing the incidence direction of external illumination, suggesting the possibility of using this effect (and its extension to non-periodic surface features) for far-field patterning and for long-distance plasmon-based interconnects in plasmonic circuits, energy transfer, and related phenomena.
