The logarithmic plots of \({Z}_{xx}^{\mathrm{inf}}\), \({Z}_{yy}^{\mathrm{inf}}\), \({Z}_{xy}^{\mathrm{inf}}\), and \({Z}_{yx}^{\mathrm{inf}}\), and \({T}_{x}^{\mathrm{edge}}\), and \({T}_{y}^{\mathrm{edge}}\) on the x-axis for the case of \({\mathbf{R}}_{x}^{T}\left(45^\circ \right){\widehat{{\varvec{\rho}}}}_{{\varvec{y}}}{\mathbf{R}}_{x}\left(45^\circ \right)\) equaling a \(\left[\begin{array}{ccc}{\rho }_{xx}& 0& 0\\ 0& 275 & 225\\ 0& 225& 275\end{array}\right]\) with \({\rho }_{xx}\) = 5000, 500, 5 and 0.5 Ω-m, b \(\left[\begin{array}{ccc}50& 0& 0\\ 0& {\rho }_{yy} & 225\\ 0& 225& 275\end{array}\right]\) with \({\rho }_{yy}\) = 5000 and 2000 Ω-m, c \(\left[\begin{array}{ccc}50& 0& 0\\ 0& 275 & 225\\ 0& 225& {\rho }_{zz}\end{array}\right]\) with \({\rho }_{zz}\) = 5000 and 2000 Ω-m, and \(\left[\begin{array}{ccc}50& 0& 0\\ 0& 275 & {\rho }_{yz} \\ 0& {\rho }_{yz}& 275\end{array}\right]\) with \({\rho }_{yz}\) = 30, 3 and 0.3 Ω-m. The indices are all with reference to \({\mathbf{R}}_{x}^{T}(45^\circ ){\widehat{{\varvec{\rho}}}}_{{\varvec{y}}}{\mathbf{R}}_{x}(45^\circ )\), when \({\widehat{{\varvec{\rho}}}}_{{\varvec{y}}}=\left[\begin{array}{ccc}50& 0& 0\\ 0& 500 & 0\\ 0& 0& 50\end{array}\right]\)
