Abstract

We present requirements, analysis, and comparison of available measurement systems designed or potentially appropriate for measurement of induced electric and magnetic fields generated by hand held transceivers in lossy bodies. This comprises thermocouple, diode- dipole, diode-loop probes, pyroelectric and Hall effect sensors, and optical sensors. It has been shown that optical sensors are the best for near fields measurements in lossy bodies. This comes from their dielectric and passive nature, and hence small field perturbation. They offer possibility of field measurement in a wide frequency (up to several GHz) and dynamic ($GT 100 dB) range. These sensors also provide a good compromise between the sensitivity and spatial resolution, with the possibility of further improvement by utilizing integrated optic technology.
