摘要：

The electromagnetic properties of nanometer-sized manganese dioxide and silica dioxide/manganese dioxide composite in the frequency range 2-18 GHz are discussed in this paper. Findings show that MnO2 is a kind of dielectric loss media with broad frequency bandwidth. Moreover, with the increasing of the MnO2 filing proportion, the wave absorbing peak values drift to the lower frequency band. Analyses of transmission electron microscope (TEM) micrograph and electromagnetic parameters of MnO2 particulate show that its wave attenuation property can be attributed mainly to its flaky and strip-shaped topography and high dielectric constant.
