Abstract

Carbon-ferrite microwave absorbers were designed experimentally and fabricated trialy, as a result of which the relative frequency bandwith of 7.3 to 8.2% were obtained under the tolerance limits of the reflection coefficients lower than -20 dB, and the matching thickness becomes 1.4 to 1.6mm, which is significantly thinner than that of the conventional ones. Furthermore, attenuation has been founded by measuring the material constants of the microwave absorbers for microwave oven and the results are compared and discussed.
