仿真可以帮助弥合概念验证阶段和介电泳器件工程之间的差距。我们提出了一种模拟方法，克服了基于流体流的方法的限制。在我们的蒙特-卡罗-泊松模拟器中，胶体系统被描述为粒子分辨率。这个特性允许考虑体积力和粒子-粒子相互作用，通常在连续近似中被忽略。反过来，可以模拟大量的粒子和大系统，以满足器件设计的需要。在一个实验验证的案例研究中，我们讨论了高密度和中等密度制度中的多粒子相互作用的作用。
Simulations can aid to bridge the gap between the proof-of-concept stage and the engineering of dielectrophoretic devices. We present a simulation method overcoming the limits of fluid-flow based approaches. In our Monte-Carlo-Poisson simulator, the colloidal system is described at the particle resolution. This characteristic allows for taking into account volume forces and particle-particle interactions usually neglected in the continuum approximation. In turn, large number of particles and large systems can be simulated to meet the device design needs. In an experimentally verifiable case study, we discuss the role of the multi-particle interaction in high and moderate density regimes.
