Variation of the electromagnetic (EM) field distribution in the anechoic box is calculated by finite difference time domain (FDTD) method. It is confirmed that quantitative relation between the performance of the wave absorber and the variation of EM field distribution under the condition that two types of the absorbers are installed with the wall of the box. Moreover, the effectiveness of the measurement of the anechoic box by using FDTD method is confirmed because the tendency of the analytical result of the magnetic field distribution is similar to its experimental result.
