E-Field probe for measuring the exposure occurred by mobile phones in phantoms

The explosion-like spread of mobile telecommunication raises the problem of the exposure of the user to the electromagnetic field. The most realistic experimental investigations of the exposure can be made in phantoms. An E-Field probe has been developed for this purpose. The isotropic probe consists of three mutually perpendicular short dipole antennas with zero-bias diodes in the gap and highly resistive wires to the preamplifier. The device can be applied in liquid phantoms. The technical details and first measurements are given.
