Measurement of temperature inside open TEM-cell with thermal camera

Open TEM-cell can be used for calibration of small antennas as well as for exposing biomedical samples and small animals to the electromagnetic fields. Open TEM-cell is missing its sidewalls thus allowing easier access to equipment under test being less stressful for live test subjects at the same time. Less stress comes from the fact that there is light and air available without losing the cell electric properties. When exposing live tissue to RF radiation, it is always necessary to exclude the thermal effect. That is why it is important to measure temperature inside the TEM-cell. Open TEM-cell enables use of thermal camera which shows changes in temperature depending on the power coming from the RF generator.
