Abstract

The distribution of the electromagnetic field in a transverse-electromagnetic-field (TEM) cell, loaded with various equipment-under-test (EUT), is calculated using the finite-element method (FEM). The calculations are performed for a two-dimensional (2-D) configuration for inhomogeneous dielectric-conductor EUTs of various cross-sectional dimensions. The set of curves obtained provides a means of estimating the uncertainty of the TEM cell measurements and can be used as a quick reference guideline for predicting the maximum dimensions of the EUT for a given field distortion.<>
