{$$T$$}-coercivity for scalar interface problems between dielectrics and metamaterials. (English) Zbl 1276.78008
The authors study mathematical aspects of well-posedness of boundary conditions for harmonic electromagnetic fields at dielectric-metamaterial interfaces. They set up and analyze the corresponding criteria for different boundary geometries that involve the knowledge of local material coefficients.
