Paper Abstract

We present optical sensors for the measurement of electric and magnetic fields in an anatomically and dielectrically correct biological phantom of the human head generated by a personal communication device. The sensor is based on all-dielectric optical probes, coupled by fiber optics to the remote light sources and signal processing electronics. The electric field probe utilizes Pockel's effect in cadmium telluride, while the magnetic field probe is based on Faraday effect in cadmium manganese telluride. The anticipated measurement sensitivity is 2 V/m (E field) and 0.25 (mu) T (H field), with spatial resolution of 1 cm. Frequency range is 1.8 GHz, and dynamic range is > 60 dB. Both sensors utilize polarimetric optical scheme.
