对远场的相速特性作了较详细的分析。文中首先从电磁场有限元出发对轴向和径向上的似稳态场相速度作了仿真研究，发现其在空间某些位置上具有稳定的相速，与波特点相似。同时分析了参数μ，σ，ｆ对相速的影响。结果表明，其与电磁波在良导体中传播规律的定性分析相符。最后本文还对瞬态激励下的远场涡流效应作了一定分析，结果再次证明其具有似波特性。 The phase velocity characteristics of the far field made a more detailed analysis. Starting from the finite element of the electromagnetic field, the steady-state field velocities in the axial and radial direction are simulated and found to have a stable phase velocity at some positions in space, similar to the wave point. At the same time, the influence of the parameter μ, σ, f on the phase velocity is analyzed. The results show that it is consistent with the qualitative analysis of the propagation of electromagnetic waves in a good conductor. Finally, we analyze the far-field vortex effect under transient excitation, and prove again that it has wave-like characteristics.
