Analysis of EM absorption reduction using paper based negative indexed metamaterial shielding

In this paper, a paper based negative indexed metamaterial is proposed for electromagnetic absorption reduction of portable wireless devices. The metamaterial structure has been designed and characterized using FIT technique based EM simulator CST Microwave studio. The main outcomes of the paper are EM absorption reduction by 14.23% and 15.3% at 0.9 GHz and 1.80 GHz, respectively using metamaterial shielding.
