The transmission properties of terahertz THz wave in metal-coated hollow waveguide are studied. Based on the characteristic equation of THz electromagnetic wave in metallic hollow waveguide the dependence of the transformation attenuation and phase constant on the frequency of THz wave inner radius of the waveguide and conductance of the metal material is simulated by using the Newton-Raphson iterative method. The results show that the transformation attenuation can be decreased effectively by using large radius waveguide and high conductance coating metal.
