摘要

提出了一种利用有限体积时域法和蒙特卡罗算法计算非均匀介质有效介电常数的方法。计算了自由空间背景下各种球形夹杂介质在较大体积分数范围内的结果。与理论边界和介电混合物模型的比较表明，该方法可用于中至高体积分数。

Numerical homogenization of heterogeneous media using FVTD simulations

We present a method to calculate the effective dielectric constant of an inhomogeneous medium using the finite-volume time-domain (FVTD) method and a Monte Carlo algorithm. Results for a variety of spherical inclusion dielectrics in a free space background are calculated over a large range of volume fraction. Comparison with theoretical bounds and a dielectric mixture model showed that the method can be used for moderate to high volume fractions.
