Abstract :
In this paper, effect of target conductivity on plasmonic cloak performance is investigated. The target considered here is a conducting/semiconducting sphere, enclosed in a plasmonic cloak designed for PEC sphere. Structure was modelled and simulated in HFSS. Bistatic and monostatic RCS for cloaked and uncloaked structure was evaluated for various values of target conductivities. High reduction in both monostatic and bistatic RCS was observed even for conductivity value as low as 0.01Sm-1.
