中文摘要：

基于复合介质单位体积电场能量守恒，得到了复合介质的有效介电常数，以文献给出的有效介电常数模型为基准，验证了文中结果的有效性。结合现有文献，研究了降雨及沙尘暴的有效介电常数，结果表明：降雨的有效介电常数随温度敏感的变化，当能见度较大时，沙尘暴有效介电常数的变化可以忽略；算法简单明了，为研究其他复杂介质的电磁波传播做了有益的探索。

英文摘要：

The effective permittivity of dielectric mixtures is presented in this paper based on elec- tric energy conservation of a unit volume for the dielectric mixtures. Its validity is tested by comparing its result with that from the available references about effective permittivity~ Based on the reference the effective permittivity for rainfall and sand dust-storm are researched. Simulations show that the effec- tive permittivity for rainfall varies sensitively with the temperature and that variation with the visibility for the sand dust-storm may be ignored under the case of a large visibility. The algorithm used in this paper is simplicity. It has been a beneficial exploration of electromagnetic wave propagation in other di- electric mixtures.
