Nowadays, microplastics pollution has become a global concern as it endangers the ecology, marine animals, and cause health threats to human beings. This paper attempted to simulate an optical planar waveguide sensor for microplastics detection in water via Wave Optics Module-COMSOL Multiphysics®. The analyte refractive index was ranged from 1.4800 to 1.5000 RIU, in reference […]
