Abstract:In this work, the broadband wave鄄transparent materials were prepared via the composite of multilayer
frequency selection surface( FSS). Meanwhile, the FSS was made with conductive metal material platinum through
screen printing process, and porous nitride ceramic materials were used for medium support of FSS. Detailed analyses
are made for microstructure and properties of the wave鄄transparent materials. As a result of the study, multilayer FSS
struture shows excellent overlapping and consistent cycle; the FSS compostion is stable and acquires a dense structure
layer with well conductive properties; also the multilayer ceramic and metallic FSS has transmittance of 95% at 9. 5 to
18 GHz frequency.
