Abstract
The surface plasmons (SPs) capability to affect the field localization within a Bragg structure is discussed in this paper. The effects induced by the presence of a silver layer on the formation of a resonant mode are analyzed as well, showing that SPs do actually aid the formation of an enhanced resonant mode, which is not able to localize when SPs are not well supported by the metal. The numerical analysis highlights the dramatic ability of a SP to localize light at certain wavelengths, even though the mechanism is affected by losses, which have been estimated replacing silver with a perfectly electric conductor layer.
