A kind of porous core photonic crystal fiber (PCF) for terahertz (THz) wave propagation is proposed in thispaper. By intentionally rotating the porous core lattice structure, a dispersion of 1.06 ± 0.12 ps/THz/cm ina frequency range of 0.5–1.08 THz is observed. Also, a very low material absorption loss (0.066 cm1) andlow confinement loss (4.73 104 cm1) at the operating frequency f = 1 THz are obtained. Besides,single-mode properties, power fraction in air core and frequency response of the proposed PCF are alsoanalyzed. The reported design can be fabricated easily using stack and draw method and be used inpotential applications in the THz region.
