Case II: fundamental harmonic components of \(E_{{\text{r}}}\) along the closed field line in the noon-meridian plane at \(L = 8~R_{{\text{E}}}\). Left: the eigenstructure oscillations of fundamental harmonic of \(E_{{\text{r}}}\) between \(t = 50 - 200~\Omega _{{i0}}^{{ - 1}}\) in time sequence. Right: the wave power spectra of the fundamental harmonic of \(E_{{\text{r}}}\) by using plane wave analysis
