Analysis Of Calibration Arrangements For AC Field Strength Meters

This paper presents numerical calculations for two kinds of arrangements used for calibration of AC field strength meters: a vertically symmetrical parallel-plate and a non-symmetrical plate-to-plane arrangement. Factors affecting the field distribution were analyzed with high accuracy, such as ratio of the electrode separation to the plate dimension, effect of an introduced meter and a grounded wall. The non-symmetrical arrangement is easier to use, but the symmetrical arrangement is more immune to the perturbing effects. Some of calculations were compared with the analytical approximation or with the experiment.
