Detailed Documentation

This research focuses on simulating magnetotelluric response curves for two-layer media using MATLAB programming. The implementation involves solving Maxwell's equations through numerical methods, where we calculate impedance tensors and apparent resistivity profiles using frequency-domain electromagnetic modeling. Through analysis of these response curves, we can better understand the properties and characteristics of two-layer media structures. The MATLAB code utilizes key functions including: - Boundary condition handling for layer interfaces using impedance matching algorithms - Frequency-domain electromagnetic field calculations with vectorized operations for efficiency - Response curve visualization using semilog plots for apparent resistivity and phase spectra Additionally, this study investigates factors influencing magnetotelluric responses in two-layer media and explores methods to optimize these response curves. We examine how different medium materials and structural parameters affect response characteristics, and how this information can enhance our understanding of magnetotelluric phenomena. The code includes parameter sensitivity analysis functions that systematically vary layer thickness and conductivity values to study their impact on response curves. The implementation employs matrix operations for efficient computation of electromagnetic field propagation across layer boundaries, with special attention to numerical stability at high-frequency ranges. Results are validated through comparison with analytical solutions for simplified cases.
