Abstract

•Analysing GEBG characteristic with equivalent circuit.•Dynamically adjusting the electromagnetic wave propagation in ribbon arrays GEBG.•Resonance characteristic can be dynamic adjustment in concentric rings GEBG.•Spurious passband can be efficient suppression in spiral-GEBG.

Electromagnetic band-gap structure with slow-wave effect is instrumental in effectively controlling electromagnetic wave propagation. In this paper, we theoretically analyze equivalent circuit model of electromagnetic band-gap structure based on graphene and evaluate its potential applications. Graphene electromagnetic band-gap based on parallel planar waveguide is investigated, which display good characteristics in dynamically adjusting the electromagnetic wave propagation in terahertz range. The same characteristics are retrieved in a spiral shape electromagnetic band-gap based on coplanar waveguide due to tunable conductivity of graphene. Various potential terahertz planar devices are expected to derive from the prototype structures.
