Seismo-electric for both seismic and electric sources Code is for a layered acoustic and electric medium. Seismic calculated at a time step delta_t, the electric and magnetic fields calculated at a smaller time step within delta_t. Seismic calculated on a smaller grid than the EM calculations. At appropriate time steps pressure is interpolated onto the EM grid and/or electric fields interpolated onto the seismic grid. This version takes into the air-earth interface for both seismic and EM wave fields. Solutions of coupled first order Maxwell's equations are solved in the two dimensional environment using a finite- difference scheme on a staggered spatial and temporal grid. The acoustic equations (where shear is ignored) are obtained from the poroelastic governing equations. The acoustic equations are solved using a finite-difference approach with a staggered grid in space and time.
