在微波波段，测量了铁硫半导体硫铁矿和磁黄铁矿在0.3 ~ 1.1 μm和1.5 ~ 3.0cm处的光学复折射率。在可见光和紫外线区域的折射率的吸收和折射分量的行为表明，土星环上公布的数据是合理的。铁硫与水冰和斜方辉石顽火辉石的组合与太阳系形成的平衡冷凝模型相一致;水冰和斜方辉石也被近红外观测数据所建议。这些物质的组合可以解释迄今为止在环光谱中看到的所有光谱特征。水冰中少量陨硫铁在低温下的微波行为与雷达反射率和无线电发射率数据一致。
Optical complex indices of refraction for the iron-sulfur semiconductors troilite and pyrrhotite have been measured between 0.3 and 1.1 μm, and at 1.5 and 3.0 cm in the microwave region. The behavior of the absorptive and refractive components of the index in the visual and ultraviolet regions suggests a reasonable match to published data on Saturn's rings. A combination of the iron sulfur with water ice and the orthopyroxene enstatite is consistent with an equilibrium condensation model for the formation of the solar system; the water ice and an orthopyroxene are also suggested by near-infrared observational data. A combination of these materials could explain all spectral features seen in the ring spectra to date. The microwave behavior of a small quantity of troilite embedded in water ice at low temperatures is consistent with the radar reflectivity and radio emissivity data.
