Terahertz (THz) circular photonic crystal fiber (CPCF) with the similar distribution of air holes as that in variable-size circular photonic crystal in polyethylene material was introduced. Guiding and dispersion properties of the CPCF with different parameters have been accurately computed. Results show that the CPCF is a useful terahertz waveguide which has good ability to confine THz fields, low group-velocity dispersion parameter and low relative dispersion slope. Furthermore, the polyethylene material that is transparent to terahertz wave is inexpensive and easy to operate.
