Assessment of EM absorption in muscle cube with metamaterial attachment

The purpose of this paper is to calculate the specific absorption rate (SAR) reduction in muscle cube with metamaterial attachment. The finite-difference time-domain (FDTD) method has been used to evaluate the SAR in a realistic anatomically based model of the muscle cube. We design the single negative metamaterials from periodic arrangement of split ring resonators (SRRS). By properly designing structural parameter of SRRS, the effective medium parameter can be trade negative at 900 MHz and 1800 MHz band in this paper. Numerical results of SAR values in muscle cube with presence of resonators exhibit SAR reduction. These results can provide useful information in designing safety mobile communication equipment compliance.
