采用蒙特卡罗方法和有限元方法模拟了由两种不同材料组成的复合物的介电常数。在高介电常数材料的高浓度范围内，介电常数的模拟值呈现出“平行模型”的趋势。另一方面，在高介电常数材料的低浓度范围内，化合物表现出“串联模型”样行为。在高介电常数材料含量约为65%时，其表现出类似于对数混合规则的结果。在仔细考虑这些结果后，一个新的方程来预测的化合物的介电常数。新方程计算的介电常数与实测值之间的一致性优于以前报道的任何其他情况。
The dielectric constant of a compound consisting of two different materials was simulated using the Monte Carlo and finite element methods. In the high concentration range of the higher dielectric constant material, the simulated value of the dielectric constant showed a “parallel-model”-like tendency. On the other hand, in the low concentration range of the higher dielectric constant material, the compound showed a “serial-model”-like behavior. Around 65% content of the higher dielectric constant material, it exhibited results similar to the logarithmic mixing rule. After careful consideration of these results, a new equation to predict the dielectric constant of the compound was derived. The agreement between the dielectric constant calculated by the new equation and the measured values was better than in any other case reported before.
