Experiments were conducted to observe and record the effectiveness of a fence acting as an electromagnetic barrier to the field emanating from a horizontally polarized electromagnetic pulse EMP simulator. The experimental results are compared to a theoretical model which predicts the observer height and range dependence of the electric field due to Fresnel diffraction. The comparison reveals good agreement, with typical uncertainties being on the order of 10 percent.
