[en] Using the quasistatic approximation, we calculate the dispersion relations for plasmonic waves along a chain of
metallic nanoparticles when the host is a nematic or a cholesteric liquid crystal (NLC or CLC). If the director
of the NLC is perpendicular to the chain, the doubly degenerate transverse (T) branches split into two linearly
polarized branches. For a CLC with a twist axis parallel to the chain, the two T branches again split, but are
no longer linearly polarized. We illustrate these results numerically by calculating the dispersion relations for
Drude metal particles in either an NLC or a CLC.
