利用太赫兹(THz)时域谱系统研究了应力对太赫兹波的影响。通过琼斯矩阵法，根据实验系统推导出实验原理。实验结果表明，聚四氟乙烯的折射率与外加应力呈线性关系。这一结果可应用于太赫兹波的折射率或相位的主动调制。(C)2013年美国光学学会
Experimental tests are presented to investigate the stress effect on terahertz (THz) waves with a THz time-domain spectroscopy system. Through the Jones matrix method, an experimental principle is derived according to the experimental system. Experimental results indicate the linear relationship between a polytetrafluoroethylene refractive index and applied stress. The result can be applied to the active modulation of a refractive index or phase of a THz wave. (C) 2013 Optical Society of America
