Abstract
Summary Based on neglecting the anomalous electromagnetic (EM) fields under Green’s integral operator, Born Approximation is an important approach to obtain the fast solution of the EM integral equations (IE). In the half-space conductivity, Born Approximation could precisely reflect the truly information of the anomalous conductivities embedded in the half-space, which the data is collected on the ground. Comparing to the method of finite difference (FD) and finite element (FE), IE could solve the problem in comparative low time-consuming and high precise, while the “anomalous induction number” does not get too large. Take advantage of the method of IE, the abstract computes the EM field induced by anomalous conductivity in halfspace region. Born inversion is also considered basing on the work has been done previously. It demonstrates that Born method, no matter of the forward modeling or inversion, is a high useful and efficient way in geophysical data processing.
