E-Field Measurement, Accuracy and Uncertainties

E-fleld measurement is essential in EMC both in far and near field areas especially for dosimetry, SAR evaluation and dielectric material characterization. Measurement devices of E-field usually consist of two main components: a small antenna or other pickup device that is sensitive to the presence of an E-field (in the case of radiation) and a detector to convert the signal to a form that can be registered on a readout device such as a meter (both for radiation and guided- waves). An overview on these instruments, their accuracy, errors and uncertainties is presented.
