Magnetotelluric method
WebBy using the weighted residual method， we derived the three-dimensional MT finite element equation. The three-dimensional vector finite element hexahedral meshing mode was introduced and the basis functions were selected. Then we derived the three-dimensional magnetotelluric vector finite element stiffness coefficient matrix and … WebJun 1, 2024 · Magnetotelluric method Krylov subspace 1. Introduction The magnetotelluric method is often used in detecting the electrical characteristics of underground targets, due to its wide band range (10−4 -10 4) and large detection depth.
