Recently, reflected electromagnetic wave radiation from obstacles or electronic equipment or causes a serious problem. There are bad interferences in surface of the building or huge bridge to increase the ghost image on television or marine radar screen. The absorbing materials such as resistance sheet, dielectric mixed carbon, rubber sheet mixed with ferrite powder and sintered ferrites were ,investigated at many institution as the absorbing materials in order to reduce the radiation noise. In this paper. in order to absorb the electromagnetic energy, thin type of the new absorbing materials were investigated. From the experimental results it is concluded that the amount of reflection agree well with results from theoretical calculation.
