Can mur-diff calculate the scattering of penetrable objects of negative permittivity?

Hello,
Thank you for your interest - sorry for the delay. I've never tried it, and never studied it. Technically, you could try it, there is no problem - but I do not ensure that the result is good :)

What would change mathematically for the boundary integral equations or the integral representation of the solution?
