Abstract：
The electromagnetic properties of magnetic fly-ash hollow cenosphere in the frequency ranges 2-18 GHz were studied in this paper. A number of experiments show that the complex permittivity and permeability of magnetic fly ash hollow cenosphere with three size and three magnetism is a kind of microwave absorbent, Due to the conductive behavior of Fe2O3, Fe3O4 and SiO2, high dielectric can be obtained in microwave frequencies. Findings show that the reflection loss band width of 60% vol. magnetic fly-ash hollow cenosphere composite is 6.6 GHz above 5 dB.
