Abstrakt		It is well known that specific absorption rate (SAR) values are dependent on permittivity values. However, variability in the published permittivity values for human and animal tissue and the development of sophisticated 3-dimensional digital anatomical models to predict SAR values have resulted in the need to understand how model parameters affect the predicted whole body and localized SAR values. In this report, we establish the partial derivative of whole body and localized SAR values with respect to permittivity values of all tissue types, as well as for only the tissues with the most variable permittivity values as reported by Hurt et al.
