Fig. 3From: Multi-order vector finite element modeling of 3D magnetotelluric data including complex geometry and anisotropyTop panel shows the magnitude of stretching factor from Fang and Wu (1996), for fixed parameters \(a_0=100\) and \(b_0=10^{-10}\). Bottom panel shows that from Zhou et al. (2012), with \(a_{\text{min}}=0\), \(a_{\text{max}}=100\), \(b_{\text{min}}=10^{-2}\), \(b_{\text{max}}=10^6\)Back to article page
