  Large research articles based on graphene have been published in various
areas since 2007 due to its unique properties. Among these designed structures,
graphene-based plasmonic waveguides are one of the interesting subjects in
communications. In this paper, a historical review of plasmonic graphene
waveguides is presented. The graphene-based waveguides can be divided into two
main categories 1- rectangular and 2- cylindrical waveguides. In both
categories, graphene can be only electrically biased or magnetically and
electrically biased simultaneously where the conductivity of graphene becomes a
tensor in the second case. Therefore, we have four main categories for
plasmonic graphene waveguides which are studied and discussed more precisely in
this paper.
