Sensitivity in Head Tissue

Frequency:                                                  1900 MHz

Epsilon:            40.0 (+/-5%)                            Sigma:              1.40 S/m (+/-5%)


ConvF

Channel X:          5.5

Channel Y:          5.5

Channel Z:          5.5

Tissue sensitivity values were calculated using the load impedance of the APREL
Laboratories Daq-Paq.


Boundary Effect:
Uncertainty resulting from the boundary effect is less than 2% for the distance
between the tip of the probe and the tissue boundary, when less than 2.44mm.


Spatial Resolution:
The measured probe tip diameter is 5 mm (+/- 0.01 mm) and therefore meets the
requirements of SSI/DRB-TP-D01-032 for spatial resolution.

To minimize the uncertainty calculation all tissue sensitivity values were calculated
using a load impedance of 5 MΩ.

Boundary Effect:

For a distance of 2.4mm the evaluated uncertainty (increase in the probe sensitivity)
is less than 2%.
