제안 방법
- However, a significant increasing of local SARs for a smaller head as in [1] was not observed in any case. Although the models nsduced evenly in all directions fom the SAM model do not represent those of typical children or diffrent races, we made sure that the results in this letter will offer useful data for the effects of head sizes on SAR, considering the pressed auricle and various bar-type phone models.
- The finite-difEerence time-domain (FDTD) method was used with sixteen perfectly matched layers, and all models were discretized with the uniform grid of 1 x 1 x 1 mm3. The spatial peak SAR values over 1 voxel, 1 g, and 10 g, and the current and voltage amplitudes at the antenna terminal of each phone model were calculated and compared.

- In this letter, we report the relation between head size and peak SAR values fom a more general standpoint using various phone models with different electromagnetic characteristics, the specific anthropomorphic mannequin (SAM) head model, and the test position of IEEE Std 1528 [6].
