P191 3-D EM MODELING AND INVERSION WITH GREEN’S TENSOR INTEGRATION IN WAVENUMBER DOMAIN Summary 1 SEONG-JUN CHO 1 YOONHO SONG 1 JUNG HEE SUH 2 and SEUNG-HWAN CHUNG 1 1 Korea Institute of Geoscience and Mineral Resources. 30 Kajung-dong Yusung-gu 305-350 Daejon Korea We have developed an efficient three-dimensional (3-D) electromagnetic (EM) modeling and inversion algorithm based on localized nonlinear (LN) approximation suggested by Habashy et al.(1993). We introduced unit cell Green’s tensor integration algorithm in wavenumber domain for the sake of reducing memory requirement while maintaining the accuracy. Integration of Green’s tensors is to be done through the inverse
