Abstract
In this paper, we consider some Poisson-type equations arising from the study of electromagnetic wave propagation in metals and metamaterials, where sign-changing coefficients in these equations lead to challenges that fall outside standard frameworks. We apply the T-isomorphism method, expanding on the approach in [1], to analyze Poisson-type equations in fully asymmetric configurations. These configurations require a new construction of isomorphism T. Finally, we obtain the well-posedness of these problems under certain parameters
