Magnetotelluric 2D Forward Modeling Program

I have developed a MATLAB-based magnetotelluric 2D forward modeling program that incorporates two distinct modes: TM (Transverse Magnetic) mode and TE (Transverse Electric) mode. The implementation utilizes finite-element or finite-difference methods to solve Maxwell's equations in heterogeneous media. The TM mode simulates electromagnetic wave propagation perpendicular to the Earth's surface, typically implemented through Ez field component calculations with appropriate boundary conditions. The TE mode handles electromagnetic wave propagation parallel to the Earth's surface, focusing on Hz field component computations with layered medium modeling. The program architecture includes mesh generation modules, field calculation algorithms, and data visualization tools. Key functions involve impedance tensor calculations and apparent resistivity transformations using Fourier analysis techniques. This program serves applications in geophysics and resource exploration, enabling deeper investigation of subsurface structures and properties through electromagnetic response simulations. By analyzing the modeled data, researchers can gain enhanced understanding of Earth's internal characteristics, thereby advancing exploration of geological mysteries.
