We eliminate $$\mathbf{e}$$ using

$\mathbf{e} = \mathbf{M^e_{\sigma}}^{-1} \left(\mathbf{C}^{\top} \mathbf{M_{\mu^{-1}}^f} \mathbf{b} - \mathbf{s_e}\right)$

and solve for $$\mathbf{b}$$ using:

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

Note

The inverse problem will not work with full anisotropy
