By eliminating the magnetic flux density using

\[\mathbf{b} = \frac{1}{i \omega}\left(-\mathbf{C} \mathbf{e} + \mathbf{s_m}\right)\]

we can write Maxwell’s equations as a second order system in \(\mathbf{e}\) only:

\[\left(\mathbf{C}^{\top} \mathbf{M_{\mu^{-1}}^f} \mathbf{C} + i \omega \mathbf{M^e_{\sigma}} \right)\mathbf{e} = \mathbf{C}^{\top} \mathbf{M_{\mu^{-1}}^f}\mathbf{s_m} - i\omega\mathbf{M^e}\mathbf{s_e}\]

which we solve for \(\mathbf{e}\).
