摘要：

通过太赫兹时域光谱技术对新型准同型相界组分的三元系弛豫铁电单晶铌铟镁酸铅–钛酸铅[0.24Pb(In1/2Nb1/2)O3– 0.43Pb(Mg1/3Nb2/3)O3–0.33PbTiO3 (0.24PIN–0.43PMN–0.33PT)]进行测试，并采用时域有限差分法(FDTD)，研究了不同厚度和不同电场诱导下单晶的THz波介电调制特性。结果表明：在0.1～1.0 THz频率范围内，厚度和电场都是影响材料介电调制性能的主要影响因素。在0.325 THz处，厚度分别为3、5和7 μm时，对应的THz波调制深度分别为31.4%、43.7%和49.9%；在不同电场条件下，在0.543 THz处，调制深度达到了18.3%，而在0.903 THz处，调制深度达到了23.7%。

The ternary system relax or ferroelectric single crystal of [0.24Pb(In1/2Nb1/2)O3?0.43Pb(Mg1/3Nb2/3)O3?0.33PbTiO3, (0.24PIN?0.43PMN?0.33PT)] with the MPB composition was investigated by terahertz time-domain spectroscopy. The THz wave dielectric modulation properties of this single crystal were examined by finite difference time domain (FDTD) at different thicknesses and in various electric fields. The results show that the thickness and the electric field both have dominant effects on the dielectric modulation performance at 0.1–1.0 THz. At 0.325 THz, the modulation depths of THz wave are 31.4%, 43.7% and 49.9% when the thicknesses are 3, 5 μm and 7 μm, respectively. The modulation depths are 18.3% and 23.7% at 0.543 THz and 0.903 THz, respectively, in different electric fields.
