Enhanced electromagnetic stealth property of SiO2f/ Silicone resin composites by metasurface through integration of absorption and scattering

Abstract

In this paper, the design and characterization of SiO2f/ silicone resin composites with functional metasurface through integration of absorption and scattering were conducted. The SiO2f/Silicone resin composites with multilayer had a checkerboard metasurface and a basement with quartz fiber reinforced magnetic material. Owing to the scattering function for electromagnetic wave of the metasurface, destructive interference can occur and reduce reflection. Additionally, the resulting composites could also absorb more energy through multiple electromagnetic resonances excited by the metasurface. The designed SiO2f/ Silicone resin composites with a thickness of 2 mm, were shown by simulation to produce low reflection less than −10 dB in the range of 9.1GHz–17.2 GHz. The fabrication and measurement of a prototype were conducted. The experimental results basically accord well with the simulation value. The electromagnetic stealth property of SiO2f/Silicone resin composites was successfully enhanced by the metasurface through integration of absorption and scattering.
