The dielectric properties of copper catalysts were measured and their influences on the microwave assisted combustion of diesel soot were investigated. It was found that the complex permittivity data of the copper catalysts were between those of diesel soot and filter substrate material, cordierite, showing that the catalysts were able to absorb microwave and hence to promote the ignition. In comparison to the combustion without catalyst, the power required for a 50% burnoff of carbon could be reduced by about 700W and the average CO 2 mole fraction in the combustion products was increased from about 60% to about 90%.
