It bridges the gap between microwave and optical wavelength and has already confined the researcher interest due its potential applications in spectroscopy, non-invasive imaging, biomedical sensing, astronomy, security sensitive areas such as monitoring drugs, explosives or weapons in a non-destructive manner, hybridization of DNA and communications. A large number of the existing THz system are bulky and rely on free space propagation due to the lack of low-loss transmission waveguides in the THz spectrum. Therefore, the investigation of low-loss, commercially feasible, efficient and flexible waveguides for the exultant execution of THz scheme becomes incapable of being disregarded. In this research, performance and properties of a porous core dielectric fiber has been studied to find a suitable THz waveguide for communication applications. A novel type of hybrid core porous fiber design has been developed using TOPAS material. Propagation characteristics for different fiber core porosity and core diameter have been studied with different percentages of core areas. The effects of rotating the triangular air hole arrangements in the hybrid core region on propagation have been studied for the proposed design. Simulation results show a flat low EML of 0.0398±0.000416 cm -1 from 1.5 to 5 terahertz (THz) range with negligible confinement and bending loss with 17.89% core area of the total fiber. Also the reported waveguide exhibits a near zero flat dispersion at 0.4±0.042 ps/THz/cm in the frequency range from 1.25 to 5.0 THz. The reported novel design and innovative results with special features have indicated the noteworthy potentiality of the proposed porous core fiber as a reliable THz waveguide for communication applications. 2016 2021-11-02T02:06:28Z 2021-11-02T02:06:28Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/72678 en Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Computer and Communication Engineering
