Electric field sensors and temperature probes are necessary resources for the evaluation of the potential effects of radiofrequency (RF) electromagnetic fields (EMF) on biological media. In this study, the RF EMF measurement capability of an electro-optic (EO) probe is presented. This millimeter-size probe covers more than seven decades of frequency bandwidth and allows simultaneous measurement of electric-field and temperature variations. The EO probe performance is characterized through linearity, dynamics and selectivity measurements carried out in a TEM cell and a cuvette filled with a biological solution. The media are exposed to 1800 MHz continuous-wave (CW) signals representative of GSM phone signals.
