Abstract Many modern composites consist of dielectric polymer matrices containing embedded spherical particles. These particles can be electrically conducting and often have magnetic properties. In order to accurately model and simulate such materials, precise calculation of the electrical capacitance between identically sized spheres is required. This is of particular relevance at microscopic dimensions where many smart material-based micro devices are concerned. This may appear trivial for a small number of particles. However, many methods or their analysis appear to be questionable or not applicable at reduced dimensions. In this work, the various methods of analysis are scrutinized before being compared with both simulation and direct measurements. It is surprising to note that of the many works investigated only 3 are in close agreement with both simulation and measurement.

两个导电球之间的电容分析

摘要 许多现代复合材料由包含嵌入球形颗粒的介电聚合物基质组成。这些颗粒可以是导电的并且通常具有磁性。为了精确建模和模拟此类材料,需要精确计算相同尺寸球体之间的电容。这在许多基于智能材料的微型设备所涉及的微观维度上尤其重要。对于少量粒子,这可能显得微不足道。然而,许多方法或其分析似乎有问题或不适用于缩小的维度。在这项工作中,在与模拟和直接测量进行比较之前,仔细检查了各种分析方法。
