Elshorbagy, Mahmoud Hamdy Mohamed ; Cuadrado Conde, Alexander ; González Contreras, Gabriel ; González Contreras, Francisco Javier ; Alda, Javier | IEEE | 2019-03-27In this paper, we present a plasmonic refractometric sensor that works under normal incidence; allowing its integration on a fiber tip. The sensor's material and geometry exploit the large scattering cross-section given by high-contrast of the i[...]
