Graphene is an interesting debated topic between scientists because of its unique properties such as tunable conductivity. Graphene conductivity can be varied by either electrostatic or magnetostatic gating or via chemical doping, which leads to design of various photonic and electronic devices. Among various graphene-based structures, plasmonic graphene filters have attracted the attention of many researchers because of their various applications in THz frequencies. There are four main types of graphene filters proposed in the literature, which are: 1- Circular filters, 2- Planar filters, 3- Periodic filters, and 4- Other types of filters (which are not categorized in any of the other three groups). This paper aims to study and investigate various types of graphene-based filters published in the literature.
