摘要

A theory for treating terahertz (THz) surface wave propagation on conical metal wire waveguides is presented. The expression for describing surface wave propagation on the conical wire waveguide is obtained based on the Sommerfeld surface wave model. According to the theory, the surface wave propagation on the conical copper wire waveguide is investigated by the numerical calculation, and the results obtained agree well with that of experimental measurement by Y. B. Ji et al. Furthermore, both the surface wave propagation properties of the conical copper wire waveguides versus the wire diameter and versus the THz wave frequency are studied by the numerical calculation. The work presented provides a theoretical basis for describing surface wave propagation on the conical THz metal wire waveguide and is quite useful for designing this kind of waveguides.
