The absorption spectrum of the suggested MMA at different analyte refractive indices. During this study, the geometrical parameters have the initial values (\({R}_{i}\) = 1.8 mm, \({D}_{i}\) = 0.25 mm, \({L}_{h}\) = 0.8 mm, \({W}_{h}\) = 0.25 mm, \({R}_{o}\) = 4 mm, \({D}_{o}\) = 0.25 mm, \({L}_{v}\) = 1.25 mm, and \({W}_{v}\) = 0.25 mm.)
