Query: Comparison of Tensor Boundary Conditions (TBCs) with Generalized Sheet
  Transition Conditions (GSTCs)   This paper compares Tensor Boundary Conditions (TBCs), which were introduced
to model multilayered dielectric structures, with Generalized Sheet Transition
Conditions (GSTCs), which have been recently used to model metasurfaces. It
shows that TBCs, with their 3 scalar parameters, are equivalent to the
direct-isotropic -- cross-antiisotropic, reciprocal and nongyrotropic subset of
GSTCs, whose 16 tangential (particular case of zero normal polarizations) or 36
general susceptibility parameters can handle the most general bianisotropic
sheet structures. It further shows that extending that TBCs scalar parameters
to tensors and allowing a doubly-occurring parameter to take different values
leads to a TBCs formulation that is equivalent to the tangential GSTCs, but
without reflecting the polarization physics of sheet media, such as
metasurfaces and two-dimensional material allotropes.
