摘要：

Active frequency selective surface (AFSS) absorber loaded with PIN diodes is a new type of structural absorber with tunable absorption properties. This absorber is similar to a sandwich, the surface is an AFSS, the middle is a dielectric slab of surface absorbing material, and the bottom is a metallic ground. In order to design and fabricate a thin and good performance absorber, the selection of dielectric slab of surface absorbing material is very important. In this paper, we detailed investigated the effects of the dielectric slab of surface absorbing material parameters (permittivity and thickness) to the absorption properties by experiments, and an experimental equation was proposed to provide a better description about their relationship. The measured results indicated there was an optimum thickness for the dielectric slab of surface absorbing material to produce the broadest bandwidth. The experimental equation was useful to optimize the design of the absorber.
