| Resumo: | The proposal of this work is to present a simulation with project results for a plasmonic
sensor based on a "rib" waveguide, which is translated into Portuguese as "costela".
The structure was designed considering a wavelength of λ = 632.9 nm, allowing the
observation of the sensor's performance based on the variation of the refractive index
of an analyte material. Ultra-thin layers of gold were added to separate the guiding
region composed of titanium dioxide (TiO2), forming a microchannel to deposit the
analyte. The propagation channel, composed of TiO2, a gold layer, and the analyte,
was deposited on a substrate composed of diatomite. The system was simulated using
the Finite Element Method (FEM) to obtain the electric field intensity, effective
refractive index, and confinement losses. |
