Detecting geomagnetic field nonlinearities by bispectral analysis and a phase coupling nonlinear technique

The Earth's magnetic field varies over a wide range of characteristic times, say, from years to centuries, and more. In order to detect some nonlinear features of the geomagnetic field evolution we first apply a nonlinear spectral technique, i.e. bispectral analysis, to the secular variation of...
