| Summary |
Electromagnetic fields under large-scale modeling have become important research in the field of geophysical electromagnetic sounding. Although most of our previous studies have been based on horizontal layered models, the curvature of the earth should be considered as the scale of the investigation increases. Therefore, we use the full wave method to rederive the formula in spherical coordinates by introducing the concepts of transmission and reflection, considering the existence of displacement current in the air layer and the coexistence of polarization and conductivity of underground media. Finally, the propagation characteristics of electromagnetic fields of different frequencies are analyzed. The necessity of considering the curvature of the earth for large-scale modeling is illustrated by comparing the results with those under the planar model. |
