The use of fiber optics is increasing day by day due to their low transmission losses. Nowadays, researchers are working hard to make the transmission more efficient with extremely low-loss fibers. Based on a porous-core topaz suspended in suspension, this design incorporates a square lattice-shaped core fiber. Since most of the components are exceptionally as an absorber of THz waves, it presents a major obstacle to achieving low dissipation waveguides for effective THz propagation. We propose a design that exhibits a highly low effective material loss (EML) of 0.03 cm-1 at a 1.0 THz operating frequency for a 330 µm core length. Furthermore, for the ideal design parameters, the fiber has a confinement loss of 0.05 dB/cm and a dispersion of 0.48 ± 0.04 ps/THz/cm. Other important expansion characteristics, such as the power fragment and single-moodiness, may also be fully researched.
