7. Tissue Simulating Liquids
For SAR measurement of the field distribution inside the phantom, the phantom must be filled with
homogeneous tissue simulating liquid to a depth of at least 15cm.For head SAR testing, the liquid
height from the ear reference point (ERP) of the phantom to the liquid top surface is larger than
15cm. For body SAR testing, the liquid height from the center of the flat phantom to the liquid top
surface is larger than 15cm, which is shown in Fig. 7.1. For body SAR testing, the liquid height
from the center of the flat phantom to the liquid top surface is larger than 15 cm, which is shown
in Fig. 7.2.Thenominaldielectricvaluesofthe tissue simulating liquids in the phantom and the
tolerance of 5%are listed in below table.
