Abstract
In this paper, we use the split ring resonators (SRR) to reduce the EM interaction between a dipole antenna and a muscle cube. By properly choosing the geometric parameters of SRR, the permeability can be negative at 900MHz and 1.8GHz. It is found that the specific absorption rate (SAR) in the muscle cube can be reduced by placing the designed SRR between the dipole antenna and the muscle cube. The performance of the antenna with SRR is also studied. Numerical results are demonstrated to validate the effect of SAR reduction.
