Although accurate numerical solvers for 3-D direct current (DC) isotropic resistivity models
are current available even for complicated models with topography, reliable numerical …

We examine the one-dimensional direct current method in anisotropic earth formation. We
derive an analytic expression of a simple, two-layered anisotropic earth model. Further, we …

In frequency-domain seismic wave modeling, absorbing artificial reflections is crucial to
obtain accurate numerical solutions. We have determined that, in viscoelastic anisotropic …

We integrate three advanced numerical techniques—Gaussian quadrature grid (GQG)
discretization, a new generalized stiffness reduction method and the latest version of an …

Effective‐medium theories for either highly conductive or more resistive electrical inclusions
in a moderately conducting background medium are presented for modelling macroscopic …

The direct current (DC) resistivity method has been widely applied in engineering,
environmental, and hydrological geophysics as well as field mining, geothermal exploration …

电各向异性广泛存在于自然界中, 已成为电磁勘探资料解释中不可忽视的因素.
特别是在一些沉积岩地区, 由于层理发育导致地下介质电阻率随电流方向发生变化 …
