  1. 1. Inversion of 2D Magnetotelluric and Radiomagnetotelluric data with Non-Linear Conjugate Gradient techniques

    University essay from Uppsala universitet/Geofysik

    Author : Dominik Zbinden; [2015]
    Keywords : Numerical solutions; inverse theory; non-linear conjugate gradients; preconditioning; electromagnetic theory; magnetotellurics;

    Abstract : I implemented and tested the method of Non-Linear Conjugate Gradients (NLCG) to invert magnetotelluric (MT) and radiomagnetotelluric (RMT) data in two dimensions. The forward problem and the objective function gradients were computed using finite-difference methods. READ MORE

  2. 2. A note on electromagnetic field theory and 1D modeling of synthetic CSAMT data

    University essay from Uppsala universitet/Geofysik

    Author : Hannes Hellsborn; [2009]
    Keywords : ;

    Abstract : Controlled source audio magnetotellurics, or CSAMT, is one of the principal methods for electromagnetic measurements. A 1D model is a simple representation but a quite easy way to find the main features of the Earth's subsurface. The 1D inversion of CSAMT data that has been used in this report was presented by H.M.
