Comparison between the prescribed results from the PKUES kinetic dispersion solver and those reconstructed using the analysis methods adopted in this study. (a), (b) Three components of the synthetic electric and magnetic field time series generated by PKUES for a test wave event. (c), (e), (g) Timescale spectra of the three components of the prescribed current density. (d), (f), (h) Corresponding current density spectra reconstructed using the ALB-WCDS method described in Section 2. (i), (k) Energy conversion rate spectrum and effective electromagnetic energy change rate spectrum computed from the prescribed current density. (j), (l) The same quantities derived from the ALB-WCDS-reconstructed current density.
