DOI: 10.1109/tgrs.2022.3232488
Abstract: We present an efficient scheme for computing 3-D magnetotelluric (MT) forward responses. The scheme is especially valuable for large models resulting from fine discretization or the large survey area. The proposed approach overcomes the iterative… read more here.
