Zhdanov, Michael S. | New approach to interpretation of airborne magnetic and electromagnetic data | We present a new technique for underground imaging based on the idea of space-frequency filtering and downward continuation of the observed airborne magnetic and electromagnetic data. The technique includes two major methods. The first method is related to the downward analytical continuation and ... | 1996-01-01 | |

Zhdanov, Michael S. | Quasi-linear approximation in 3-D electromagnetic modeling | The Born approximation in electromagnetic (EM) numerical modeling has limited application for solving 3-D electromagnetic induction problems, because in structures with high conductivity contrasts and at high frequencies, this approximation is inaccurate. In this paper, we develop a new and rel... | 1996-01-01 | |

Zhdanov, Michael | Three-dimensional quasi linear electromagnetic inversion | One of the most challenging problems of electromagnetic (EM) geophysical methods is developing three-dimension(a3l- D) EM inversion techniques. This problem is of utmost importance in practical applications because of the 3-D nature of the geological structures.T he main difficulties in 3-D inversio... | 1996-01-01 | |

Zhdanov, Michael S. | Underground imaging by frequency-domain electromagnetic migration | A new method of the resistivity imaging based on frequency-domain electromagnetic migration is developed. Electromagnetic (EM) migration involves downward diffusion of observed EM fields whose time flow has been reversed. Unlike downward analytical continuation, migration is a stable procedure tha... | 1996-01-01 |
