13504 文中利用太赫兹时域光谱(terahertz time-domain spectroscopy, THz-TDS)技术对DMSO掺杂PEDOT:PSS薄膜在太赫兹波段的介电常数进行研究,结合Drude-Smith模型计算了DMSO掺杂PEDOT:PSS薄膜的载流子浓度和载流子迁移率,全面分析了DMSO掺杂PEDOT:PSS薄膜的介电性能。 In this study, the dielectric properties of DMSO-doped-PEDOT:PSS films were investigated using terahertz time-domain spectroscopy(THz-TDS) measurements. The values of the carrier density and mobility were also determined by fitting the dielectric permittivity to the Drude-Smith model. The properties of PEDOT:PSS films can be changed by adjusting the doping concentration.
13505 研究表明:薄膜的介电性能可以通过调节掺杂量而改变,当掺杂浓度提高至15 vol%时,薄膜表现出金属特征,而未掺杂和低掺杂浓度的薄膜仍然表现半导体特征。 When the doping concentration is increased to 15 vol%, the film exhibits metal characteristics, while the pristine and low-doped film still exhibits semiconductor characteristics.
13506 针对电大尺寸目标高频散射场的仿真, 采用物理光学 (physics optics, PO) 算法来求解。 In this paper, we adopt the physical optics (PO) method to obtain the high frequency scattered fields from electrically large scatterers.
13507 由于PO积分为高振荡积分, 传统的数值求积方法非常耗时, 文中提出了数值最速下降路径 (numerical steepest descent path method, NSDP) 算法来计算。 Because the PO integral is highly oscillatory, the conventional quadrature rules like Gauss quadrature rule is very time-consuming. Hence, we propose a numerical steepest descent path method (NSDP) to handle this problem.
13508 首先, 通过对振幅函数和相位函数二次拉格朗日函数插值, 得到二次曲面片上PO积分标准形式。 We use the Lagrange interpolation method to get the quadratic amplitude and phase functions.
13509 其次, 通过变换积分路径, 将高振荡PO积分转化为最速下降路径上的积分, 大大减少了计算复杂度。 Then, we transform the highly oscillatory integrand into a smooth and rapidly decreasing function by distorting the integral paths.This method greatly reduce the computational workload than brute force method.
13510 NSDP算法进一步将PO积分转变为驻相点、谐振点和顶点的贡献, 具有鲜明的物理意义。 The NSDP method could divide the PO integral into several critical points contributions like stationary phase points, resonance points and vertex points in physical insights.
13511 数值算例证明了NSDP算法具有精度误差可控和频率无关的特性。 The numerical results demonstrate that this method has advantages of error-controllable and frequency-independent.
