This work presents a method of moments (MoM) analysis for conducting bodies composed of surfaces connected to thin wires in multilayered uniaxial anisotropic media, such as often occurs in modeling geophysical problems. Wire, wire-to-surface junction, and RWG bases are used to model electric currents on the thin wire, junction, and conducting surfaces, respectively. Based on the transverse equivalent network (TEN) analogy with transmission lines, the dyadic Green's function for multilayered uniaxial media is efficiently evaluated using Kummer's method to accelerate the spectral integral contributions by extracting their asymptotic spectral forms, which are later restored in spatial forms derived from the Sommerfeld identity; this also reduces the spatial singularities of the spectral integrals such that they may be efficiently interpolated using a simplex interpolation scheme. A major contribution of this work is to model surface-to-wire junctions for structures penetrating layer boundaries in a multilayered uniaxial medium. In addition, a proper numerical scheme for modeling thin wire structures in multilayered uniaxial media is proposed.
