提出了一种新的洛伦兹时域有限差分法(FDTD)来分析运动复杂介质的散射场。与其他方法不同，我们提出了一种在运动系统中引入入射平面波的特殊方法。利用Lorentz变换和线性内插技术，将散射场从运动系统变换到系统的其余部分。数值结果验证了该方法计算移动介质平板散射场的准确性和有效性。
A novel Lorentz finite-difference time-domain (FDTD) method was proposed to analyze scattered fields from moving complex dielectric in this letter. Different from other methods, we present a special way to introduce the incident plane wave in the moving system. The scattered fields are transformed from the moving system to the rest of the system with the Lorentz transformation and linear interpolation technique. Numerical results verify the accuracy and validation of the proposed method to calculate scattered fields from moving dielectric slabs.
