在对远场涡流的机理解释上，国际上一直存在波与非波两种截然不同的观点．本文通过解析分析和电磁场有限元数值计算对远场涡流的相速基本特性进行了分析，发现尽管场量满足电磁扩散方程，但似稳态下场在空间某些位置上传播时具有似波现象．此外本文还对瞬态激励下的远场涡流似波特性作了进一步讨论．本文的研究对于进一步促进远场涡流技术的应用具有一定的参考价值
In explaining the mechanism of turbulence in the far field, there are two totally different opinions about wave and non-wave in the world. In this paper, the basic characteristics of the velocity of the far-field vortex are analyzed by analytical analysis and the finite element numerical calculation of the electromagnetic field. It is found that although the field satisfies the electromagnetic diffusion equation, the steady-state bottom field has the phenomenon of wave-like when it propagates in some places in space. In addition, the far-field vortex-like characteristics under transient excitation are further discussed. The research in this paper has some reference value to further promote the application of far-field eddy current technology
