太赫兹辐射在压块中的散射是非常感兴趣的，因为它有可能非破坏性地评估各种结构元素，如压块中的颗粒尺寸和缺陷。在这项研究中，我们隔离的散射贡献的损耗系数的硼硅酸盐玻璃微球悬浮在聚四氟乙烯（PTFE）紧凑的太赫兹时域光谱测量。微球的颗粒尺寸和浓度在压块中是不同的，以解决它们对太赫兹散射的影响。
Scattering of terahertz radiation in compacts is of great interest due to its potential to non-destructively assess various structural elements such as particle size and defects in compacts. In this study, we isolate the scattering contributions to the loss coefficient of borosilicate glass microspheres suspended in a polytetrafluoroethylene (PTFE) compact measured by terahertz time-domain spectroscopy. The particle size and concentration of microspheres in the compacts were varied to resolve their effect on terahertz scattering.
