Design of a Narrow Band Filter Based on a Photonic Crystal Cavity for CO<sub>2</sub> Sensing Application
This paper investigates the use of a miniaturized filter based on a triangular lattice of holes in a photonic crystal (PhC) slab. The plane wave expansion method (PWE) and finite-difference time-domain (FDTD) techniques were utilized to analyze the dispersion and transmission spectrum, as well as th...
