6. 5. Developing data processing program for a new radio magnetotelluric (RMT) instrument

   University essay from Uppsala universitet/Geofysik

   Author : Elis Uebel; [2022]
   Keywords : RMT radio magnetotellurics matlab GUI;

   Abstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE
