A novel Zeonex based porous fibre is proposed for biomedical imaging and polarisation preserving applications of terahertz waves. The standard finite element method is used to simulate the propagation characteristics of the fibre that shows high numerical aperture of 0.48, high birefringence of 0.039 and a flattened dispersion of 1.07 ± 0.05 ps/THz/cm. In addition, the fibre also possesses low effective material loss and negligible confinement loss in the terahertz frequency band.
