Recovered inducing field coefficient \(\varepsilon _{2}^1\) in the frequency domain using full-VP. Three frequency bands (left: 1 day; middle: 10 days; right: 100 days) are shown. The windowed spectra are split into real parts (upper panel) and imaginary parts (lower panel). In each subplot, the inversion results (cyan for real parts and light pink for imaginary parts) are shown together with the windowed spectra of the ground truth (thick blue and red lines)
