Terahertz wave reflection and transmission of carbon nanotubes slab are investigated in this paper. The wave and current equations that describe characters of terahertz wave in dispersive carbon nanotubes (CNTs) are presented and discretized by using the auxiliary differential equation (ADE) in the finite-difference timedomain method (FDTD), because the permittivity of CNTs are frequency-dependent. The ADE-FDTD method and program’s efficiency is proved by the reference's analytical method. Numerical results show that the transmission coefficient of single wall carbon nanotubes (SWCNTs) does not show distinct peaks and dips at Terahertz frequency. The multiple transmitted pulses of silicon dioxide bi-covered with SWCNTs are observed. The electromagnetic interference (EMI) shielding effect of SWCNTs, double wall carbon nanotubes (DWCNTs) and Hydrogen doped CNTs are compared.
