APPENDIX D: SAR TISSUE SPECIFICATIONS Measurement Procedure for Tissue verification: 1) The network analyzer and probe system was configured and calibrated. 2) The probe was immersed in the tissue. The tissue was placed in a nonmetallic container. Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle. 3) The complex admittance with respect to the probe aperture was measured 4) The complex relative permittivity ε’ can be calculated from the below equation (Pournaropoulos and Misra): j 2ωε r ε 0 b b π [ ] exp − jωr ( µ 0ε r' ε 0 )1 / 2 Y= [ln(b a )]2 ∫ ∫ ∫ a a 0 cos φ ′ r dφ ′dρ ′dρ where Y is the admittance of the probe in contact with the sample, the primed and unprimed coordinates refer to source and observation points, respectively, r 2 = ρ 2 + ρ ′2 − 2 ρρ ′ cos φ ′ , ω is the angular frequency, and j = −1 .

APPENDIX E: SAR SYSTEM VALIDATION Per FCC KDB Publication 865664 D02v01r02, SAR system validation status should be documented to confirm measurement accuracy. The SAR systems (including SAR probes, system components and software versions) used for this device were validated against its performance specifications prior to the SAR measurements. Reference dipoles were used with the required tissue- equivalent media for system validation, according to the procedures outlined in FCC KDB Publication 865664 D01v01r04 and IEEE 1528-2013. Since SAR probe calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration point, using the system that normally operates with the probe for routine SAR measurements and according to the required tissue-equivalent media. A tabulated summary of the system validation status including the validation date(s), measurement frequencies, SAR probes and tissue dielectric parameters has been included.

Modulations in the table above represent test configurations for which the measurement system has been validated per FCC KDB Publication 865664 D01v01r04 for scenarios when CW probe calibrations are used with other signal types. SAR systems were validated for modulated signals with a periodic duty cycle, such as GMSK, or with a high peak to average ratio (>5 dB), such as OFDM according to FCC KDB Publication 865664 D01v01r04.
