Scalar potential formulation for a gyrotropic inhomogeneous medium

Summary form only given. Vector potentials are frequently utilized in the electromagnetic analysis of problems involving simple (i.e., linear, homogeneous, and isotropic) media. In recent decades, various scalar and vector potential formulations have been investigated for the analysis of anisotropic and bianisotropic media. This interest has been greatly influenced by the significant developments in material fabrication capability and the phenomena associated with complex media. Gyrotropic anisotropic materials are particularly interesting due to their non-reciprocal properties.
