摘要: SUMMARY The second order partial differential equations for both the TM mode and TE are derived fromtheMaxwellequationsforadiagonalanisotropicmodel.Andthentheequationsrelatedto theTMmodearesolvedviatheFouriertransformtoobtainthequasi-analyticalsolutionsofthe 2-Dmagnetotelluric(MT)fieldsonanaxiallyanisotropicinfinitefault.Furthermore,thequasianalytical solutions tested by isotropic model corresponding to anisotropic one. Finally, MT response functions on fault models with different conductivity structures calculated, relationship between variety of conductivities is analysed, at same time some applications analytic fields in special media discussed.
