Fig. 7: MHD lensing effects with various density ratios Rρ between the CH and background plasma.
From: Resolved magnetohydrodynamic wave lensing in the solar corona
a–d MHD lensing effect at Rρ = 0.1, Rρ = 0.25, Rρ = 0.5, and Rρ = 0.8, respectively. The simulation domain includes a background coronal plasma (light blue) and an artificial MHD lens (blue) enclosed by a straight line and a parabolic curve. The values of normalization factors p0, t0, L0 for the total energy density(\({{{{{{{\mathcal{H}}}}}}}}\)), time (t), and length (x, y, z) are listed in Table 1.
