摘要翻译：
本文分析和表征了镜面和漫射元件的表面散射过程。在60GHz的中心频率下，研究了各种具有不同粗糙度的建筑材料。当用户移动很短的距离时，在一阶散射分量中观察到非常大的信号强度变化。这是由于粗糙表面散射体引起的小尺度褪色。此外，本文还研究了材料的漫射散射与材料的粗糙度、入射角和与表面的距离有关。最后，结果表明，粗糙材料的反射可能会受到高去极化的影响，这一现象可以利用偏振分集来改善毫米波系统的性能。

英文摘要：
  This paper presents the analysis and characterization of the surface scattering process for both specular and diffused components. The study is focused on the investigation of various building materials each having a different roughness, at a central frequency of 60GHz. Very large signal strength variations in first order scattered components is observed as the user moves over very short distances. This is due to the small-scale fading caused by rough surface scatterers. Furthermore, it is shown that the diffused scattering depends on the material roughness, the angle of incidence and the distance from the surface. Finally, results indicate that reflections from rough materials may suffer from high depolarization, a phenomenon that can potentially be exploited in order to improve the performance of mm-Wave systems using polarization diversity.
