Abstract
The terahertz band (0.1-10 THz), due to its high frequency and short wavelength characteristics, exhibits unique physical mechanisms in electromagnetic scattering studies. This paper focuses on targets with hyperbolic curvature (sphere) rough surfaces and proposes a joint analysis framework based on the Physical Optics (PO) method and Monte Carlo random modeling. Through theoretical modeling, numerical simulation, and THz-TDS experimental validation, the dynamic relationship between surface geometric features (RMS height, correlation length) and the terahertz scattering field is systematically revealed, providing important references for subsequent model optimization and experimental improvements.
