论文摘要
Terahertz（THZ）辐射在植物水状态监测中的应用需要有关THZ波和植物相互作用的系统研究。在这里，我们介绍了有关在不同水含量下通过植物叶子反射和传播的Thz波的散射行为的理论研究。提出了结合积分方程和辐射传递理论的理论模型，以符合测量数据。当考虑叶片厚度和表面粗糙度的变化时，良好的一致性证实了该模型的水状态评估。我们研究了THZ波在不同温度，盐度和极化下的反射和传播几何形状中对水状态监测的适用性。
The applications of terahertz (THz) radiation for plant water status monitoring require systematic studies on interaction of THz wave and plants. Here, we present theoretical investigations on scattering behavior of THz waves reflected by and transmitting through a plant leaf under different water content. A theoretical model combining integral equation and radiative transfer theory is presented to fit the measured data. Good agreement confirms the availability of the model for water status evaluation when variation of leaf thickness and surface roughness is considered. We investigate the applicability of THz waves for water status monitoring in reflection and transmission geometries under different temperatures, salinities and polarizations.
