Evaluation of EM Absorption in Human Head with Metamaterial Attachment
نویسندگان
چکیده
─ The reduction of electromagnetic (EM) absorption with metamaterial is performed by the finite-difference time-domain method with lossyDrude model by CST Microwave Studio in this paper. The metamaterials can be achieved by arranging split ring resonators (SRRS) periodically. The SAR value has been observed by varying the distances between head model to phone model, different distance, different thickness, and different size of metamaterial design. Metamaterial has achieved 53.94% reduction of the initial SAR value for SAR 10 gm. Index Terms ─ Antenna, human head model, lossy-Drude model, metamaterial, symmetry, SAR, SRRS.

Evaluation 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 designin...
