Specific absorption rate (SAR) analysis using plastic substrate based negative indexed metamaterial shielding

In this paper, a lower band negative index metamaterial is developed for specific absorption rate reduction. The proposed metamaterial is printed on the plastic cover body of the wireless device. The metamaterial structure has been designed and characterized using FIT technique based EM simulator CST Microwave studio. The perceptible outcome of this paper is specific absorption reduction using plastic substrate based metamaterial structure.
