  We report on the first study of the screening properties of the mesonic
excitations with strange ($s$) and charm ($c$) quarks, specifically the ground
states of the pseudo-scalar and vector meson excitations for the $\bar{s}s$,
$\bar{s}c$ and $\bar{c}c$ flavor combinations, using the Highly Improved
Staggered Quark action with dynamical physical strange quark and
nearly-physical up and down quarks. By comparing with their respective vacuum
meson masses and by investigating the influence of the changing temporal
boundary conditions of the valence quarks we study the thermal modifications of
these mesonic excitations. While the $\bar{s}s$ states show significant
modifications even below the chiral crossover temperature $T_c$, the
modifications of the open-charm and charmonium like states become visible only
for temperatures $T\gtrsim T_c$ and $T\gtrsim1.2T_c$, respectively.
