| Abstract: | The electromagnetic field by induction sounds in dipping borehole can be decomposed of the TE and TM waves which are independency each other,and their solutions is completely determined by two scalar partial differential equations.In the paper,we study the method to compose the electromagnetic field to TE and TM waves,give the recurrence relationship of their composite reflection and transmission coefficients,and obtain the analytic solution of the electromagnetic field in each bed,finally,we give the numerical results in several models. |
