magnetotellurics Definition and 1 Threads
Magnetotellurics (MT) is an electromagnetic geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface.
Investigation depth ranges from 100 m below ground by recording higher frequencies down to 200 km or deeper with long-period soundings. Proposed in Japan in the 1940s, and France and the USSR during the early 1950s, MT is now an international academic discipline and is used in exploration surveys around the world.
Commercial uses include hydrocarbon (oil and gas) exploration, geothermal exploration, carbon sequestration, mining exploration, as well as hydrocarbon and groundwater monitoring. Research applications include experimentation to further develop the MT technique, long-period deep crustal exploration, deep mantle probing, sub-glacial water flow mapping, and earthquake precursor research.

Maxwell Equations Absorbent Boundary Conditions
Hi everyone, I'm trying to understand the purpose and functionality of absorptive boundary conditions used in simulations of electromagnetic fields. Specifically, how do this conditions 1.2c): with (and ν the unit outward normal on the boundary Γ; Pτ , the projection of the trace operator)...- gltau99
