Paper Abstract

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.
