| 摘 要： | 根据强化偶极子模型推导出一个新的混合体有效介电常数的计算公式,并和Maxwell-Garnett,迭代技术模型,以及具有相干势的准晶体近似模型的计算结果作了比较.结果表明该公式比Maxwell-Garnett更接近具有相干势的准晶体近似模型的计算结果,同时比迭代技术模型,准晶体近似模型要简洁.

| Abstract: | This paper presents a kind of dipole-enhanced model for calculating the effective permittivity of a dielectric mixture. The effective permittivities calculated with this formula are compared with those obtained with Maxwell-Garnett model, iterative model, and the coherent potential-quasicrystalline approximation. The calculated result shows that the formula is acceptable. |
