**Course description**

The course will train the following abilities:

\n- \n
- Derive the differential equations governing electromagnetic (EM) induc tion in the Earth starting from Maxwell's equations. \n
- Describe EM fields owing to controlled (galvanic and inductive) and natural sources.\n
- Describe the fundamental properties of the impedance tensor and o ther transfer functions for controlled-source and natural EM fields accoun ting for galvanic distortion. \n
- Apply time-series processing to EM data and evaluate data quality. \n
- Explain the principles of numeri cal modelling like integral equation, thin-sheet, finite-difference and fi nite-element methods to solve forward problems in 2D and 3D. \n
- Exp lain how models can be calculated using inversion. \n
- Recommend a E M technique or a combination of EM techniques that is best suited to resol ve a geological target at a given depth and in a given host medium. \n
- Design field campaigns. \n
