Seismic and EM signals obtained by considering an artificial scattering effect. Once again, we consider the seven-layer half-space model and a receiver located at (− 80,890, 8680, 0.1) m. An artificial scattering effect is introduced by employing an artificial scattering conversion coefficient of Cst = 0.6 and a horizontal wave-field rotation angle of 30° in the counterclockwise direction. The simulated seismic and EM wave-fields are displayed in a Cartesian and b cylindrical coordinates, respectively
