When Reflection and Transmission Amplitude Coefficients Exceed Unity: Evanescent Waves, Resonances, and Optical Modes
Raúl de la Fuente
The reflection and transmission of propagating harmonic waves in linear optical systems have been widely discussed in the literature and are generally well understood. In passive s…

Coupled surface plasmon and resonant optical tunnelling in symmetric optical microcavities
Alejandro Doval, Yago Arosa, Raúl de la Fuente
A symmetrical structure consisting of a low refractive index dielectric layer between two metallic films, i.e. an optical cavity, surrounded by a semi-infinite dielectric medium of…

Modelling resonant transmission in a Fabry-Perot/Surface-Plasmon microcavity
Yago Arosa, Alejandro Doval, Raúl de la Fuente
Coupled surface plasmons arise in the surfaces of a dielectric layer between two metallic media when a dim wave propagating in the dielectric generates resonant free charge oscilla…
