Abstract:To detect chemicals, we proposed a photonic crystal ber (PCF) with hexagonal cladding and a hexahedron core (THz). Circular air holes (CAHs) in the vestibule provide the basis of the suggested sensor. To develop and evaluate our suggested hexahedron PCF sensor, we employed the nite element (FEM) technique and perfectly matched layers (PML), which utilized the optical parameters numerically.Here, 92.65%, 95.25%, and 90.70% are relatively sensitive, and con ning losses are low. the value 5.40×10 − 08 , 6.70×10 −… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
