Effect of magneto-dielectric nanocomposite on the SAR value of phantom model

The harmful effect of electromagnetic radiation on human body through the usage of mobile phones and other electronic equipments calls the attention of researchers to find out a remedy for the same. Thus in this study the interaction between human head model and electromagnetic field source is studied with and without shielding layer. EM wave source as a dipole antenna for GSM applications with the three layer human head model is studied using a computer simulation using CST Microwave Studio 2013. A solution for reducing Specific Absortion Rate (SAR) is addressed by the use of microwave absorber which in turn prepared through sol-gel mediated autocombustion method. Parametric analysis is introduced to optimize the dimension of the microwave absorber for shielding.
