We determine the presence of plasmonic surface modes under TE polarization in an optical fiber made of a dispersive left handed material. These modes keep clearly localized at a constant frequency within the numerical error, despite strong geometrical changes in the physical system. To prove this fact we analyze systems having random roughness on their surfaces and consider other geometry variations. The electromagnetic field distribution is determined in the region where plasmonic and non plasmonic modes exist.
