我们提出了一个全波点偶极子为基础的计划，精确的材料均匀化的复合材料。与传统的均匀化方法，采用周期性的边界条件的有效介电常数提取，所提出的技术可以有效地计算散射体之间的相互作用，即使在非均匀的混合物，以及非周期性排列的有限数量的散射体。该方法利用每个夹杂物作为基函数，从而避免了离散每个夹杂物散射体的计算负担。此外，补充分析计算提供了封闭形式的表达式来处理场奇异性和计算散射体之间的相互作用。我们表明，建议的均匀化计划可以精确地提取一个有限大小的试样的复合介电常数分布。
We propose a full-wave point-dipole-based scheme for accurate material homogenization of composites. Unlike conventional homogenization approaches which employ periodic boundary conditions for the effective permittivity extraction, the proposed technique can efficiently compute the interactions between the scatterers even in inhomogeneous mixtures as well as aperiodic arrangement of a finite number of scatterers. The method utilizes each inclusion as a basis function, and thereby sidesteps the computational burden to discretize each inclusion scatterer. In addition, the supplementary analytical calculations provide closed-form expressions to deal with the field singularities and to calculate the mutual interaction between the scatterers. We demonstrate that the proposed homogenization scheme can precisely extract the composite permittivity profile of a finite size specimen.
