Rapid SAR

Faculty: Chris Davis

Rapid SAR

  • Direct optical measurement of the temperature rise produced by the wireless device
  • Multiple (currently 12) laser beams cross a sealed phantom filled with dielectric stimulant
  • Temperature rise produced by RF energy absorption deflects the laser beams
  • Full spatial SAR measurement in less than 1 minute
  • No perturbation by electric field probes
