When ferrite hollow beads were made into coating materials, because ferrite hollow beads had hollow internal structure and conductive and magnetic ball wall, ferrite hollow beads have typical resonant ball characteristics in structure. The absorbing coating composed of numerous ferrite hollow beads could be considered as a resonant absorber. With the rapid development of information technology, especially computer technology, the introduction of computer simulation technology can often save experimental costs and reduce the blindness of experiments. Therefore, in order to comply with this development trend, this chapter will establish the absorber model of ferrite hollow bead coating based on HFSS (high frequency simulator structure) electromagnetic simulation software, and qualitatively analyze the relationship between the thickness of ferrite hollow bead coating and the resonant frequency of absorber and the distribution state of electromagnetic field inside the coating through the of computer simulation software.
