摘要：

This paper presents the application of manganese dioxide to electromagnetic wave absorber. The effective permittivity was calculated by modified Rayleigh mixing formula, and the electromagnetic wave absorbing properties of composites with different volume fractions of manganese dioxide were investigated by the comparison of calculated and experimental values in 2-12 GHz frequencies. It is found that the pure manganese dioxide holds a high dielectric constant, which is a function of frequency. The manganese dioxide composites show high absorbing performance in low frequencies, and the calculated electromagnetic properties fit the experimental values for large volume fractions used in this study.
