Measurements of site attenuation or electromagnetic noise from EUT (Equipment Under Test) are usually performed at the open field test site on the finite sized ground plane. The influence of the finite ground plane has been considered by some researchers concerning the site attenuation. The reflected wave on the ground plane was treated as it were on the infinite ground plane, in other words, the total reflection, and the diffracted wave were calculated by GTD (Geometrical Theory of Diffraction) method. However those calculations include some errors, due to the finite sized ground plane and its edge. So we calculated the electric field near the ground plane by the FDTD (Finte Difference Time Domain) method to make clear the reflection and the diffraction of the finite sized ground plane for horizontal and vertical polarization.
