Description
Summary:In this article, a highly sensitive hollow-core photonic crystal fiber (PCF) is proposed and numerically investigated for the application of different chemical identification in the terahertz regime. Commercially available COMSOL Multiphysics software is used to evaluate the sensing and propagation characteristics of the proposed sensor. The numerical analysis informs that extremely high relative sensitivity around 98% can be achieved from the sensor at optimum structural condition. Moreover, at optimum structural dimension and operating frequency significantly low effective material loss (
