Abstract	The effect on the electric field of a foam block in a GTEM cell was numerically investigated using the finite integration (FI) method. In particular, we focused on the frequency range of 1–16 GHz, for which the effect has not yet been sufficiently analyzed. We only modeled the tip of the GTEM cell, to focus on the change in the electric field strength from the foam block and also to reduce the computational resources required. We showed that the foam block increases the electric field strength when it is placed at the tip of the GTEM cell. Even though the change in the electric permittivity was small, the effect on the electric field strength was great. We then compared the analysis results with measurement results and found that good agreement was obtained between the two. We also investigated the effect that the size of the foam block has on the electric field. The electric field strength was found to increase when the block size increased. We concluded that the foam block may affect the electric field and increases the electric field strength in a GTEM cell.
