摘要 The linear boundary element method for electromagnetic fields is taken to deal withthe excitation of a non-symmetrical electric dipole in a lossy half space.A simple and practicalalgorithm is offered to the Measurement While Drilling with Electromagnetic waves(EM-MWD),The calculation for two models under the low frequency limits are compared with the experimentsand the results calculated with the theory of stationary current fields.
