A Scattering Model Based on GTD in Terahertz Band
Scattering center is the basic electromagnetic scattering characteristic of targets in optical region. In this paper, the parametric scattering center model is analyzed for application to THz band. Then a reduced scattering center model is derived. This model is simpler than parametric scattering model and suitable to the scattering mechanisms in THz band. On this basis, experimental results are analyzed and the validity of the scattering center model in THz band is verified.
