论文摘要

在这项研究中,模拟了由旋转运动引起的非惯性作用对圆柱形完美斗篷的影响。同样,研究了平面波,高斯正弦和高斯脉冲之间的相互作用。结果表明,非惯性完美的斗篷可以通过sagnac和磁电效应来检测。在低频的低频中,波形模式的失真是谦虚且可以忽略的,但是,当旋转频率增加时,模式失真就会变得巨大,波浪会形成且强度的增长。散射模式可以受旋转方向的影响,因此,可以通过散射模式分析来识别旋转方向。同样,可以制定一种用于测量旋转速度的方法,以使电场相滞后。通过将Maxwell的方程式从非惯性框架转换为实验室框架,使用FDTD方法计算模拟。

In this study, the impact of non-inertial effects, caused by rotational motion, on the cylindrical perfect cloak is simulated. Also, the interactions between plane waves, Gaussian sine, and Gaussian pulse are investigated. it is shown that non-inertial perfect cloak could be detectable with the Sagnac and magnetoelectric effects.at low frequency of gyration, the distortion of waveform pattern is humble and negligible, however when the rotational frequency increases, the pattern distortion becomes huge and wavelets are formed and their intensity grows up. the scattering pattern can be influenced by the direction of rotation, thus, the direction of rotation could be identified with the scattering pattern analysis. Also, a method for measuring rotational velocity can be prepared concerning the electric field phase retardation. the simulation is computed using the FDTD methods by transforming the Maxwell's equations from non-inertial frameworks to the lab framework.
