Modeling results of seismoelectric signals excited by a weight-drop source

This dataset contains data of all figures in a submitted manuscript titled \"Refining higher modes of Rayleigh waves using seismoelectric signals excited by a weight-drop source: study from numerical simulation aspect \" to Journal of Geophysical Research: Solid Earth. Effective extraction of higher mode dispersion information has been a research hotspot in the study of surface waves. In this study, we introduce a novel approach of refining Rayleigh wave higher modes by using seismoelectric signals, namely, electromagnetic (EM) signals originating from seismoelectric conversion. Adopting a weight-drop source, we simulate seismic and EM signals for a homogeneous half-space and six multi-layered porous models (see data for Figure 1). An extended version of the frequency-Bessel transform method is introduced to extract dispersion information from seismic and EM signals.

Using a homogeneous water-saturated half-space porous model, we firstly investigate the dispersion characteristic of sei...
