Impact of rectangular resonator width variation on sensor transmittance. (a) Transmittance spectra for widths varying from 0.2 μm to 1 μm in 0.2 μm steps, revealing a non-monotonic change in transmittance. (b) Transmittance drop percentages as a function of width, indicating reduced attenuation and higher transmittance at larger widths due to diminished electromagnetic confinement.
