When increasing the frequency, inductive effects start to limit the currentand skin effect makes it increasingly difficult to resolve the current distribution in thewinding. At sufficiently high frequency, the current is mainly flowing in a thin layernear the conductor surface. When increasing the frequency further. capacitive effectscome into play and current is flowing across the winding as displacement currentdensity. When going through the resonance frequency, the device goes from behavingas an inductor to become predominantly capacitive. At the self resonance, the resistivelosses peak due to the large internal currents Figure 4 shows the surface current3 MODELING OF A 3D INDUCTORSolved with COMSOL Multiphysics 5.0distribution atl MHz.

代码中的plot_hht函数实现了Hilbert-Huang变换(HHT)，HHT就是Hilbert-Huang Transform（希尔伯特黄变换），美国航天航空局黄鳄教授发明的，大概的过程是：先对信号进行经验模态分解（Empirical mode decomposition －EMD），得出本征模态函数（IMF intrinsic mode function），再对本征模态函数进行希尔伯特变换，从而过进一步得该信号的希尔伯特谱、时频能量谱等，以便对信号进行分析，据介绍对非线性及非平稳信号有较好的分析和处理效果。
