The Dirac plasma considered here models a solid state system, recently realized graphene monolayer, where the conduction electrons obey the Dirac-like equation and exhibit a linear in momentum dispersion relation. Theoretical work presented here is based on the the dielectric response function and the dynamical structure function within the Random-Phase-Approximation (RPA).9 pages, 5 figures, submitted in Physical Review BMesoscale and Nanoscale Physicstext
