论文摘要
可以配置静态电场以引导沿电场线的带电的纳米颗粒。某些现场线配置可以将纳米颗粒聚焦于处方的地方，从而充当电动漏斗。尽管Funnels对于纳米载具有重要性，但缺乏表述和理解。我们在两个维度（2D）中提出了两个可解的模型，因为它允许一个模型使用复杂的平面来精确计算现场线。一种模型处理两个固定的偶极子，以便外部电场试图挤压它们之间，从而形成漏斗。另一个处理几个平行的导电板和一个孔，外部场还通过创建一个漏斗。获得的结果可能对于配置纳米覆盖工程的电场很有用。
Static electric fields can be configured to guide charged nanoparticles along the electric field lines. Some field line configurations can focus the nanoparticles to prescribed places thus acting as electric funnels. Despite the importance of funnels for nanoprinting , there is a lack of formulation and understanding. We present two solvable models in two dimensions (2D) as far as it allows one to use the complex plane for exact calculation of the field lines. One model deals with two fixed dipoles such that the external electric field tries to squeeze through between them thus forming a funnel. The other one deals with a couple of parallel conducting plates with a hole where the external field comes through also creating a funnel. The results obtained may be useful for configuring the electric field for nanoprinting engineering.
