Abstract
Methyl Bromide, Ethyl Bromide, Chloropicrin, 1,3-dichloropropane, are harmful organic chemical substances used in poultry feed as pesticides. Previous studies show a strong evidence of their associations with cancer risk in some cases. The detection method of these substances is very tough without chemical experts and can be even very time consuming. We propose a modified Dodecagonal photonic crystal fiber (PCF) for detecting these harmful chemical. Through numerical analysis it is shown that the introduced PCF can provide the relative sensitivity value of about 77.5% for methyl bromide, 77% for ethyl bromide, 79% for 1,3-dichloropropane, 79.8% for chloropicrin at the operating wavelength of 0.7μ m which are quite higher than previous results. Full-Vectorial Finite Element Method (FEM) is utilized for carrying out the numerical analysis of the presented structure.
