The shielding effect of a new material composed of rubber with carbon and ferrite for microwave oven leakage is investigated. By adding an appropriate amount of carbon, the shielding effect is improved. A large attenuation constant, which is 6 dB/cm larger than that of a rubber ferrite, is relizable.
