What are the environmental constraints for the systems, e.g., max temperature, humidity, RF levels, power supply, etc.?
The effect of temperature changes on the SAR due to the changes of the dielectric parameters of the tissue simulating liquid is about 1%/degree, i.e., the room temperature should not change by more than 2 degrees during the measurement period. Optimal room temperature is between 20 – 24 degrees Celsius. Humidity (<80%) and RF level (SAR < 1microW/g) are not critical. For the power supply see our application note section.
