Time-domain simulating the characteristics of terahertz pulse propagation in biological tissue

Using Monte Carlo method to simulating the propagation of terahertz pulse in biological tissue and studying the interaction between the THz radiation and biological tissue. A series of diffuse reflectance curves are presented in this numerical simulation. Examination of these curves reveals that the Time-Domain propagation characteristic of terahertz pulse in biological tissue has strongly relationship with the anisotropy parameter and the absorption coefficient.
