Abstract

The finite-difference-time-domain (FD-TD) method is applied to model transverse electromagnetic (TEM) transmission cells in three dimensions. The perturbation of the TEM mode and the standard field distribution in the TEM cell, due to inhomogeneous materials placed inside the cell cavity, is evaluated. Particularly, the dependence of the disturbance of the TEM mode on the dimensions of the material and its position in the TEM cell is studied. The absorption of the electromagnetic fields in the lossy materials, placed in the cell, is also calculated
