  We study surface state plasmonics in the periodic Anderson model of a bulk
topological Kondo insulator system, involving strongly correlated f electrons
screened by weakly correlated d electrons, performing a mean-field theoretic
calculation within the frame-work of slave-boson protocol. We include the
effect of magnetic impurities as well which do not act as scattering agent in
our scheme; the exchange interaction due to them is included in the band
dispersion. The interaction opens a gap at the surface states with gapless
Dirac dispersion. We find that bulk insulation together with the surface
metallicity is possible for the system albeit only under the condition
demanding strong f-electron localization. The possibility of the intra-band and
the inter-band acoustic plasmons for the gapped surface states exists in our
report. The dominance of the bulk metallicity and the strong incarceration
capability of these plasmons are other notable outcome of the present work.
