摘要

在这项工作中，我们提出了一种高效的有限差分时域（FDTD）模拟技术，用于电离层法拉第旋转角的电磁波（EM）分析。为此，我们首先通过空间压缩因子将物理电离层建模为一个缩小的 FDTD 计算域。然后，将 FDTD 仿真计算出的法拉第旋转角乘以空间压缩系数进行校准。数值示例表明，这种新颖的空间压缩和校准技术可以为法拉第旋转角的电磁分析带来高效的 FDTD 仿真计算，而不会降低精度。

Efficient FDTD Simulation for the EM Analysis of Faraday Rotation in the Ionosphere

In this work, we propose an efficient finite-difference time-domain (FDTD) simulation technique for the electromagnetic (EM) wave analysis of the Faraday rotation angle in the ionosphere. For this purpose, we first model the physical ionosphere as a scaled-down FDTD computational domain by a space-compression factor. Next, the Faraday rotation angle calculated from the FDTD simulation is calibrated by multiplying the space-compression factor. Numerical examples demonstrate that this novel space-compression-and-calibration technique can lead to a computationally efficient FDTD simulation for the EM analysis of the Faraday rotation angle without accuracy degradation.
