Microwave Modulation Transfer: Quantitative Test of a Simplified Model Based on the Telegrapher's Equation

A simplified stochastic model for microwave modulation transfer, based on wave solutions of the telegrapher's equation, is quantitatively validated against experimental signal amplitude data. With physically plausible parameters, the model accurately reproduces observed behaviors through both analytical fitting and Random Forest regression, achieving RMSE = 0.069 and R2 = 0.944. By integrating stochastic transport effects with wave-based interpretations, the framework offers a unified perspective that extends beyond classical electromagnetic models. These results confirm the model's robustness and highlight its potential for broader applications in signal propagation analysis.
