In this Paper, the Performance of the semi-anechoic chamber which is to be constructed by the cross-shaped ferrite absorbers with broadband frequency characteristics, has been evaluated by the image method. As a result it was confirmed that the cross-shaped absorber has excellent performance over the frequency range from 30 MHz to 3,000 MHz, while the tile and the gird-type ferrite absorbers have the bandwidth of 30 - 1,000 MHz.
