GUTIERREZ VILLARREAL, Jesús Manuel et al. Enhancement of Electromagnetic Fields Under Surface Plasmon. Epistemus (Sonora) [online]. 2022, vol.16, n.32, 03.  Epub 23-Set-2022. ISSN 2007-8196.  https://doi.org/10.36790/epistemus.v16i32.172.

In this paper, the concept of surface plasmons and their applications are explained in a general way. In addition, it is shown that the Kretschmann geometry consisting of glass-metal-vacuum is one of the usually used to excite the electromagnetic field under the plasmon, because naturally on a flat surface it is not possible to get this effect, except for some particular cases of the incident source or beams combination. Also, the intensity or amplification of the field as a function of position is quantified and an important property of amplification is observed under the plasmon condition, in which the intensity of the field decays exponentially when moving away from the metal-vacuum interface. As well, is also made of research areas related to surface plasmons.

Palavras-chave : Surface Plasmon; field enhancement; Kretschmann geometry.
