- Abstract
- © 2022 The Author(s)We present a C++ package entitled 1D Controlled Source Electromagnetic Method using Quadrature With Extrapolation (1DCSEMQWE), which computes the electromagnetic field for a one-dimensional model in geophysics. This package supports the computation for both electric and magnetic dipole sources. Transmitters and receivers can be placed anywhere in the layered model. The formulation of the electromagnetic field in the frequency domain avoids using positive exponential terms, leading to higher accuracy. In particular, we introduce a new computation tool using quadrature with extrapolation for integral evaluation. Our tool addresses the numerical error occurring in the previous quadrature rule algorithm and gives users the ability to control the precision of the computed electromagnetic field.
