Confinement of light at nanoscale dimensions in plasmonic structures has many advantages including enhanced light-matter interactions. This enhancement can be well utilized in resonantly coupled atomic-plasmonic systems. In such coupled resonant systems, broad plasmonic resonance in contrast to narrow atomic resonance gives rise to reflection atomic spectroscopy with high resolution. In this paper, the reflection from thin gold layer in the vicinity of the rubidium vapor in Kretschmann configuration was modeled and the modification of hyperfine structure of the atomic spectral lines were studied. By selecting the angle of incidence of light we could change the frequency of resonance of surface plasmon-polariton mode from the central frequency of atomic resonance lines, so the EIT and Fano resonance phenomena have been observed.
