dc.description.abstractIn this paper, a novel microstructure quasi-photonic crystal fiber (Q-PCF) design is proposed. Aimed at a high relative sensitivity it is targeted for chemical sensing applications in the terahertz regime. A rigorous full-vector finite element method (FV-FEM) based numerical investigation has been applied by employing an anisotropic perfectly matched layer (A-PML) for optimizing key parameters. Improved relative sensitivity response of 78.8%, 77.8%, 69.7% are achieved for targeted analytes ethanol, benzene and water respectively at the operating frequency of f = 1.3 THz. Moreover, confinement loss, effective area, power fraction and numerical aperture (NA) are analyzed from 0.8 THz to 2.0 THz.
